手臂側面肌肉講解

好了,現在準備做一個活動式的圖表 從雙手到手臂的肢體 我們要做一個更活動式的圖表 手臂伸出來,手指的動作 可能要做一些活動式的姿勢 然後我會用我的肢體作為參考 然後我會用我的手臂作為參考 最後我會加上一段短短的短片 我會放在剪輯室,我忘了要給你們看 現在你們可以看到我的姿勢 我正在感受我的姿勢 你們之前有看過我做這個動作的其他影片 所以我才會做這個圖表 我正在感受我的肢體 感受我的肩膀 肩膀的肌肉 還有臀部的肌肉 我想把手指放在這裡 然後手臂的肌肉 手臂的細節都很簡單 用手臂的肌肉來感受 然後可能臀部的肌肉會放在這裡 這個姿勢可能是一位男性 可能是坐著或是拿著某些東西 這是一個可能性 所以我們現在開始看到臀部的肌肉 臀部的肌肉 然後臀部的肌肉 不好意思,臀部的肌肉 不是臀部的肌肉,是臀部的肌肉 把手臂的肌肉和肩膀的肌肉混在一起 這樣就可以了 這樣就有了我想要做的姿勢 現在我可以開始做更詳細的動作 開始增加臀部的肌肉 現在臀部的肌肉 我會把這個拉出來 讓你們看到我們有更多的位置 我們想要的東西 在這裡 這個球要再進一步進入臀部的肌肉 這就是我剛才示範給你們看的 但是最重要的是畫面 用你的骨骼 如果你有骨骼 如果你有一條肋骨 用它們來畫 嘗試把最多的部分畫出來 然後我們需要做一個參考 把參考畫出來 盡可能 這樣會幫助你記住所有的東西 現在是肌肉的偏偏和偏偏 在肌肉的側面 在這裡 所以他們在這裡 在這裡 從肌肉的偏偏 在這裡 不好意思 有點刺痛 在這裡 然後我們來看看肌肉的身體 回來 來,這是我們要畫的 當你把圖像集中在肌肉的位置 當然肌肉就圍起來了 但是肌肉的圖像 就是圖像 然後 Planning 把身體放在這裏,然後我們會用手臂,手臂會變得更厚 會變得更圓潤,然後會往下走 然後會往下走,然後會往下走到手臂的末端 然後我會示範用手的動作 我會用手臂來操控手臂的動作 我想要更有慈悲感的姿勢,彎曲的手臂 手臂的尖端可能會更貼近 大概靠近這個範圍 就像這樣,就像這樣 這是給你們的,也是給我 讓我看看我在畫什麼 然後到手臂的末端 然後我們會進入手臂的動作 手臂的末端會變得更有彈性 請記住手臂的末端不會移動 手臂的末端大概會移180度 然後手臂的末端會彎曲 現在我們在找手臂的末端 手臂的末端開始彎曲了一點點 但是不完全彎曲到手臂的末端 所以我們要把手臂末端的末端 或者說是手臂的末端 在這裡 所以我們要快速地量度一下 看我們在做什麼 這幫助了 確保我們能夠做到 我們能夠做到的準確度 大概在這裡,再往旁邊一點 我會調整一下,這裡有個位置 再往小一點 然後我們可以開始把手臂的末端和臀部 調整成這樣的位置 然後我們可以把手臂的末端 更具體地調整成 手臂的末端和臀部 抱歉,指標中心 然後我們可以調整臀部的末端 和臀部的臀部 然後我們可以調整臀部的末端 臀部的末端 就像一個手臂的末端 保持很鬆散,不要太堅固 然後我們要把手臂的末端 調整成更具體的方式 就像這樣 你可以看到我第一次的做法 然後看到我第二次的做法 從我推進開始,變得更準確 看到這兩個的分別嗎 這很有趣 這就是為什麼你會輕輕地拉開 讓你可以在後面調整 你的需要和你的反應 來得更準確 好,我們現在已經調整好了 我會把臀部的末端放進去 我們可以看到 它們的分別 主要是由 臀部的末端 形成一個彎曲的形狀 然後我們看到 臀部的過程 回過頭來 我們看到老手 老人的手 回過頭來 然後我們看到 臀部的過程 來自臀部的末端 在臀部 這是臀部的部分 然後在這裡彎曲 然後它會觸碰 肋骨 從這裡到那裡 它在觸碰肋骨 當然它們會把肋骨 連接在一起 然後連接在一起 然後肋骨會彎曲 然後往下走 到臀部的中心 在臀部的中心 然後遇到彎曲 從這裡到那裡 然後我們看到肋骨 它會彎曲 從這裡到那裡 然後我們看到 另一部分 我們就把它 當作開放的動作 大概線條 會在這裡 肋骨 會在這裡 肋骨 會在這裡 肋骨 會在這裡 肋骨 會在這裡 肋骨 會在這裡 肋骨 另一邊的蝦皮,背部的橫向在背部的肋骨上 記得它有一個內側的洞口 所以蝦皮的內側肌肉會在裡面 然後在上面的蝦皮肌肉也會在裡面 所以我們會看到蝦皮的內側肌肉 我們可以看到蝦皮的內側肌肉會在裡面 然後在上面的蝦皮肌肉會在裡面 所以我們會看到蝦皮的內側肌肉會在裡面 然後在上面的蝦皮肌肉會在裡面 所有三個頭,主要頭,內側肌肉,肋骨和背部肌肉 都會在裡面 所以在這裡,肋骨的三分之一 會在這裡,肩膀肌肉會在這裡 然後我們會看到肌肉的肋骨 肋骨肌肉肌肉肌肉肌肉肌肉肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌肌 I get so focused on the muscle form that it gets off a little bit It's hard to control So the triceps area will be here It's where they attach All the way down to the olecranon So I'm just getting a general feel for them here Up and over and through And they'll attach up and over Biceps brachii, brachialis underneath it And then the brachioradialis on top there As it curls over Sternum a little bit I mean it takes a lot of knowledge to do this So do a lot of copies Copy me until you get a feel for it And do your own But don't get too frustrated If they look a little awkward Because mine did for a good while Until I started to really put it all together Brachioradialis attaching in through here With the extensor carpi radialis longus Say that at a party a couple of times After a couple of drinks That should be fun But they both come together, right? In through here There's two of them And then back in here is the extensor And then the flexor carpi ulnaris As well as the extensor come together Mostly the extensor Just to give us that contouring around It bulks out here And then the end of the muscle will be And it gets more of a tendon That comes into the ulnar area Of the carpal muscles Bringing down Let's get a feel for more of the outer rib cage Maybe a little bit And then maybe that's kind of Slightly sitting down So a little bit of the rectus abdominis A little bit of the fat Maybe subcutaneous fat on top of that Just a little bit In through here And then now the contouring Of the top of the hand Which is relatively muscle-less And a little bit of the bone I'm going to push the greater metacarpal Of the thumb with the proximal distal out A little further Something like that So we get a little bit better feel of all that So there it is There's the proximal and the distal Only to the proximal No medial here Proximal, distal, or medium, middle And this is where these will all be Let's get this a little cleared up Shall we? For the bones So our first index finger metacarpal In through here It's two large knuckled condyled heads Right, like so And this is proximal, medial A little shorter And then the distal A little bit more of a point I kind of think of them as shark's teeth If you've ever seen shark's teeth If you've been to the beach You've seen you can gather shark's teeth I used to do that when I was a kid Down in Galveston in Texas My grandparents just have a beach house down there All right So medial, excuse me Metacarpal coming now to the end Where the carpals are And of course all Remember all these attach All the carpals and metacarpals Attached by dozens of ligaments Lots of ligamentation through there Crisscross and attached and over It's so complex It's fascinating It's not really needed for drawing But understanding it's pretty fun to look at it And then drawing now the metacarpals here Proximal of the ring finger down They start to curve around And get a little bit open A little bit more foreshortened Just slightly And then we have the proximal medial And then the distal will start to curve up underneath Like so More foreshortened Once you understand these bones They're really not hard to draw It just gets a little bit tedious Anatomy is tedious It's tedious But it helps your understanding of human form But you got to be able to draw gesture and volume And you've got to be able to control value And remember anatomy comes later in your learning But some of you want to go ahead and push on It's okay If you're in YouTube land Or Vimeo Or wherever you're watching These things get pirated all over It's hilarious And then now the last metacarpal here Of the pinky or last shorter finger Down and more of the side Slightly more side view of it The head and through the first condyle In the carpal phalangeal joint To the proximal Down We're really going to bend this here And then we'll bend it Now it's curving underneath And getting more foreshortened It's a tube under this The proximal This is the medial here Outward maybe a little bit further there And then of course the distal will really be curved Kind of coming back up in a U shape Back and touching the top of it Here we're coming there That's it Got it And then the last metacarpal of the thumb As it's overlapped by the other somewhat And then cleaning it up Through the proximal And just adjust the distal there I think we've got it Okay So the pollicis muscles The abductor pollicis longus Will be in through the extensor pollicis brevis We'll come through and get tendon A little filling out the forearm And then by the carpals And then tendons to the thumb So I think we're ready now to go now And start where we'll work from the distal Excuse me the deltoid And work our way down to the distal tips The fat pads of the fingers So here we go now So we're working with the biceps brachii In through here And it has its head I'll come underneath Now the coracobrachialis is there And I'll just indicate it's detached there We won't see it in this view It'll be covered up completely But that's where it's at Right in through there Now the biceps brachii will attach on top of it On the coracobrachialis in front Come down with the tendon That longer tendon And get that head going like so And then that first and second head Will roughly look together like this And we'll split them up in a moment Right in through here Will be the longer tendon And then there's the split there Roughly And then the second longer tendon Long head is on the lateral side of it So we see more of it It's major Fold our head here And it will come in down and under And it will actually go now Underneath the olecranon Okay So we can't draw it on top of the olecranon There will twist And attach to the radius And the ulna as it opens up So it's got to come underneath So it will look like here now Excuse me Here and up And I'll show you where it attaches After it comes up In through here And coming back Over and underneath On to the radius Which we wouldn't see in the ulna too as well Just to give you an indication of that It's good to know where these origins and insertions are Just to see what they're going to do There we go Of course all that's a tube Curving around In through here So brachialis will come in front With the extensor carpi Radialis longus So will come in front of that Bulk, be bulkier here And then we'll have to I'll just separate them So we can see them just a little bit And I'll curve and touch back over to The radius So they attach around the brachialis Which I forget to show here I'll go back and add a little quick addendum So you can see that Now the long head of the lateral Bicep Two heads It goes through the inner sulcus Inner tubular Sulcus And then on top of the glenoid process Right there where it attaches So it's in that little groove That keeps it locked in So there's our biceps area There's the other tendon To the cortical process It's amazing that the biceps Brachialis The two heads of the biceps Do not at all attach to the humerus Now the brachialis is underneath that somewhat A little bit hidden I'm going to make that clear When I do an addendum at the end of this video Now the deltoid We'll start to come over Lateral third of the clavicle Attaching in through here Coming on down And over These muscles The biceps Cortical brachialis And attaching with the Anterior head To the deltoid tuberosity Then I come over This is really running over here to the back And this is really kind of The where the The lateral and the posterior head meet And here's where the medial head is Roughly right in through here So we're covering up all the humerus Scapula area But we'll leave part of it to show through We just want to We want to kind of understand all of it together So we'll do This drawing will show Resonate Many different kinds of transparent Like Applications That's the point Is to be able to see all of it And know what's what's going on And then you don't really forget it You just you know You put it in your long-term memory And you start drawing it comes back If it doesn't Then you know you need still You still need work to do Before you've memorized it But you can You can memorize all this to a very Very high degree Just takes effort You look at Michelangelo's Sistine Chapel And his studies For each pose For the Ignudi The sybils and prophets And the stories of the creation stories They're all All were Were worked out poses That he observed and drew from And of course he did an anatomical studies As he did Anatomy work Cadavers and drawing from that So Lots of information So getting back to this one Deltoid Lateral head Buckles in through here a little bit Just to give you the contouring And feeling of that Remember this is over everything And attaches The deltoid tuberosity Is a real workhorse of a Of a Spot on the bone of the humerus Met halfway down on the lateral More lateral side It really works hard Bringing those deltoids in So there's the deltoid In through a curves around I'll clean this up a little bit later And make it a little bit clear It gives you some contouring around To all that as well We won't see much of the pectoralis So we know that the pectoralis comes down In over to the medial third of the clavicle And then we'll connect back up to the The greater tubercle crest Underneath Just clean this up a little bit Make that a little cleaner and clear The deltoids inserting there There's nothing easy about this It's I don't know if I make it look easy or not But it's certainly Challenging You know work And I've I've I'm not drawing from anything But I do have You can see the skeleton To the left of me And then just right out of the camera There's the Ecrugee Standing in front of me Then I've got the little hand of The right hand of it Detached And if I need I'll show you I actually pull it out in a little bit And show you The one I need But I'm not I'm not drawing from anything Observable I'm drawing from my imagination In testing my knowledge And then really Being an example for you folks You guys And then also Teaching you where these Insert These muscles are at What their shape and form is So that you can do that Now that Now we're working on the triceps So what I do is I go back and I catch the bone A little bit Clear it up This is where The two heads will attach On the scapula For the medial head Right in through there And then for the The lateral head Will be on the humerus So let's get that shape So you know I've already got the shape of The triceps So this is more of the medial part The underneath part And and then now we have Okay, so I'll show you where it's at So here's our humerus from the back Right in through here Where it'll attach The lateral And then the medial will attach To the scapula Side Where my finger just pointed this way Down to the olecranon Which we've got Twisted a little bit Or tilted So Let's clean this up a little bit As I narrate this story So sometimes I like to narrate It makes the drawing Process easier I don't have to talk During the drawing process I can just draw and then talk later So we have now the Outer head The lateral head Of the The Triceps Here the medial will be covered up mostly On those views And that tendon I'll show you how that works in a moment And we're going to get this A little bit higher I think I have to go back And there you go Let's see a little higher there Over to the Olecranon The radial part of the olecranon Through here That nice long tendon head Above the triceps Really The two The lateral and the In the medial Or the long head Here we go Okay Now the medial attaches here Tendon coming down And it bulks into its Its head position I tend to show a little bit more In this position Maybe than what you'd get But I When I went back and looked at it But I just realized I just wanted to show more of it Now we get the medial head coming down Which is actually a little bit larger and longer It's the same thing as the gastrocnemius The medial is longer and lower So we get the outer contour Which starts to work with the bicep Muscle Bicep brachialis And then they're going to come together In that a split of the head And then this turns So we get the head But it kind of turns in So we're curving contour wise this way But then we're going to get a curve Of the muscle form As it goes into the Upon the rest of the tendon The greater tendon of the tricep Which is really thick and strong And works from the edge of the Underneath part of your triceps muscle All the way down to your elbow Your Epicondyles It has a It kind of goes underneath right there So that little curve It has a way of turning in this way So And then we go to the tendons Long stranded tendons This is kind of a The upon neuroses Of the That wider area in textbooks Is real long and kind of triangular Rectangular Down to the edges of the Epicondyles here So we have a tricep muscle on Should remind you a lot of the The gastrocnemius Even though the gastrocnemius Comes down to one point At the calcaneal bone To the Achilles Now The aconius muscle That triangular muscle Right in through here Resting on Now I'm going to show you a little bit So right in through here Okay Right in through there I just took it off the écorget The pose wound up Kind of looking like this I didn't really mean for that But it came out Looking like it So there's the aconius Right in through there Very triangular kind of shape muscle So I'll put it back on the écorget In front of me I've just probably drawn it And seen it so many times That I thought okay I'll just do a pose And there it came out So I guess it's Pretty advantageous Long tendons Of the triceps Down to the epicondyle So let's clean this up Make it a little clear With a little darker chalk Charcoal Just giving some Contour striation To this drawing I'll clean that up Even further later You could spend hours Doing it like an engraving But the point is To get the knowledge And then move on Working on Splitting that head up Of the bicep a little Two heads there And then the tricep has three The medial is underneath that You don't see that too often Up underneath here Just keeping these two heads split In the deltoid First In layering Number one in layering The deltoid In the upper arm region It wraps over everything Some people put it in the shoulder I put it in the upper arm region It's kind of that nice bridge Between the upper arm And the shoulder girdle Down to the lecronon And then to the Aconeus muscle Give that some bulk Bringing that a little bit further A little bit more definition In our case here As we're drawing muscles So fold that down again Now we're going to look at the extensors We're mostly in the extensor view here The brachioradialis And the extensor carpi radialis longus The extensor digitorum Right in through here Right Polysis muscles Right The tip of the forearm And of course the extensor carpi Ulnaris And the flexor carpi ulnaris Will be at the bottom of the forearm We'll get all those And now there are more muscles than that Don't get deceived That I don't know That they're underneath there Or that we're missing some That may or may not occur We're mostly concerned With the most superficial Not that they're superficial Not smart Meaning that they're the surface They make the most surface formed Delineation That's why we don't study The pancreas or the liver When we study the abdomen We don't study the lungs That's for medical doctors We want to study bones And muscles And ligaments and tendons So that we can draw them And make the human form come alive So the extensor digitorum Remember that that's relatively in the middle And originating from the If it's extensor The more radial side So we have Now coming over and twisting Over to now And then creating the Four tendons from the Index finger to the middle To the ring to the pinky finger So we'll draw these tendons All the way over these top dorsal Dorsal tendons And remember the flex The palmar tendons The flexors is the flexor Digitorum superficialis Which gives tendons underneath Our fingers We don't I've never seen tendons underneath Because that's where fat pads are at underneath So they're all going to get covered up You see a lot of tendons on the top of the hand Especially in older folks When they age When we age Your muscular people Or sometimes you can just hang on When you're looking at your hands You'll see them in If the lighting is right If the shadows are right You can see quite a bit of tendons On the top of the hand for sure Bottom of the hand I never I never see them They're there But they're there They're there to help flex And control Now on top of those metacarpals Those tendons run across How do tendons stay on the hand Well they're wrapped By ligaments By eponeurosis ligaments All over Especially at the knuckles The joints And at the body of the shaft There's ligaments They go in X patterns too as well They criss-cross All right So now we have the extensor digitorum And now we're working with the Let's see The extensor carpi ulnaris And then the flexor Which will be to the side of it To give it the outer contour In through there So they line up pretty nicely In through here As they disappear into Their respective originating areas And we'll pop them out When they start to bulge Now remember They have a very short insertion Beginning insertion Originating from One of the two epicondyles And then their tendon Is really long So the head of the muscle The muscle body is more like a hot dog Or a Frankfurt wiener If you will And then their insertion is pretty short Up to the epicondyles But their tendons are quite long Now we have the Extensor carpi ulnaris And the flexor A little bit of the flexor We'll see to give it that final Bulkier contour On the outside of it as well These two muscles Coming together a little bit Check out the first Diagram we did If you're confused And go check the book as well Or go check the Ecorgé application Just for help too as well If you're not quite sure Where the flexors end The extensors begin And of course Where the extensors end The flexors begin We don't see the pronator teres In this view We only see it Or we see its Its residue Or its bulkiness In the more supinated Turn of the hand Where the thumb turns over We open up This one's more closed And we get the Styloid process Where the ulna was there Clean this up a little bit So we get about 10 more minutes Here's the Aconianus triangular muscle To help the joint Stabilize And I'll start to just Contour these muscles Most of it's done now And we'll just clean this up And make it clear to yourself To show you how to do that And then we're gonna drop down And put on some of the interosseous Hypothenar and thenar Areas of the Metacarpals And a little fat pads on the fingers Where we'd see them So you have to be careful with those fingers You know Sometimes from the Metacarpal phalangeal proximal joint Up to the distal They're almost done When you put the bones on tendon You just have the fat pads underneath And the nail Just to make it You know look Look more real You'll see a lot of Baroque Renaissance sculptors Will leave that area pretty Pretty Thin and fragile And it works So we have that coming down We'll get to those And through here in a moment So the pollicis muscles And through here Abductor pollicis longus So the right There There see how they come out And they kind of mimic The brachioradialis too It's like there's another Set of them So it's attachment Anyway they come from The interosseous material In the ulna The abductor longus Comes from the ulna Inside there And the brevis comes from The interosseous material But right in through here And they come out Or give a little bit more bulk To the Thumb area And those tendons Will go to the joints of the Anterior and posterior part Of the joint of the thumb To give more tendon movement In through that region And help with Reaching across the opposable thumb To touch your pinky Your ring Your middle and your index And you can grab on to that So I was reading the other night About which finger You could do away with the most And believe it or not It's your index finger Try that Stick your finger up in the air Like it's a number one And then With the three fingers in your thumb You can like You know what I can still do a lot Without it But if you lose your pinky You're losing a lot of Movement there It's interesting that way And I'm just going on A little bit of the Torso muscle serratus Anterior rib cage areas To give it more realism And now we're This is kind of Just a little clean up part of the drawing Just to make it clear for you And for the viewer And for me The artist Whatever I see Is the Your audience sees So it's got to be clear That's what we do And cleaning that up a bit Some of the darker charcoal Brachioradialis Definitely comes out We'll hide that Brachialis a little bit I'm going to include that Once the main part of this video Ends I'm going to There's a little addendum That I show you Right I just kind of clean up Where the brachialis can be I want to make sure we get that Conianus in through here The ulna Part of the elbow proper And then down in through here We get the other part of the condyle To make up that triangular Part of your elbow A little space there And then the flexor And the extensor there Carpi Ulnaris On the ulna edge The edge of the ulna Bulky head Short Origination Very long Tending to get down to this This carpal area And then the metacarpal On into the fingers As we use them Where they attach Ulnar area Where the styloid process Gets a little bulky there I'm just cleaning these up We're starting to come together Further Make these divisions A little stronger There's a lot of overlap Superficial Excuse me There's deeper muscles Deeper muscles underneath We're just concerned with More of the superficial Meaning the surface Here ulnar end And then the extensor Digitorum here One of my favorite muscles The powerful tendon And it's amazing How it will split off Into four little branches And will help control The movement of your fingertips All your fingers It's like the puppet master Up by your elbow Your elbow Your forearm muscles up there Your puppet masters And your fingers are doing the dance They're being controlled By Those Extensor and flexor muscles Polysis here The extensor radialis On the edge Polysis muscles They will bulk out a little bit They do come out They're also called When they Flex You can kind of move your hand To the side And it's called the Anatomical snuff box So a lot of people have talked about it I'll let you research that On your own You can figure out What is he talking about The anatomical snuff box Well Go and research that Just type in anatomical snuff box And it'll come up Making these a little bit Elongated with some striations Here Just about ready now to Do the Hand muscles Further Remember there are three sets Of interosseous muscles We group together The dorsal palm And the lumbrical And then we're going to start With a hypothenar over here On the palm part of the pinky Running through the side And through here There's three muscles there We group them together They're the hypothenar T-h-e-n-a-r And they give bulkiness To the palm Lateral edge Here it is Running through there And there's of course It's in conjunction With some fat pads To give you that fullness And so it begins That contour Riding through there The outside part of the Pinky Now on top Now But more to the lateral Keep that in mind Can't be on top There's not much on top Now The interosseous muscles As I'm working here They fit in between the metacarpals Dorsal on top There's palmar on the bottom Lumbrical in between A few there Those are even deeper That way they just don't show up All of that The bones The interosseous muscles Make up the bulk With the tendons They make up the bulk And excuse me The fat pads They make up the bulk Of the top of the palm And the What we think of the true palm Underneath with the ball Of the thenar muscle In the outer Kind of sausagey part Of the hypothenar And then the The metacarpal grouping On the palm Those are fat pads All that makes up that big Blocky Volumetric hand That we talk about Talk about and draw That's the block or the egg form You'll see it all the time And that's what we start with And so those muscles Inside those metacarpals Allow your fingers to spread and close Spread open and close And then we have a little bit We'll see a little bit of the thenar muscle Is it was kind of It's more webbed from the digit The metacarpal Over to the second metacarpal Through that We don't see a lot of it there Here we go So it gives you some more mobility To this opening and closing fingers Now Now we're ready for some fat pads On the metacarpals I'm going to do a couple And leave some empty Now see I'm on the lateral side of that bone I can get a little bit on the medial side of it Right in through here You see a fat pad And so the bone is curved Underneath And see how the fat pad goes over it To give Look at that That gives you that Sausagey finger like Expression Now when we start drawing from More observational references And I'll talk a little bit I'll do a couple of close-ups of fingers And nails to talk about the nail And so fat pad on the tip So if you're a guitarist Or if you play Any stringed instrument Or really anything With a tip of the finger The sensitivity That's a fat pad With nerve endings That are deeper So but there's enough space The fat pad The fat pad takes it But you develop calluses I play guitar So Like everybody in the free world Plays guitar But Those calluses develop On your tips of your fingers So that you're not Pushing on bone Fat pad Condyle Here right I'll do one Let's do the thumb We'll do the thumb And the index finger With the fat pad And we'll leave the ring And the middle off So you just see the difference Coming through here So the top you won't see a lot And we're kind of getting To the side of the thumb There's the tendon Fat pad underneath Okay That free digit there That free opposable thumb And then fat pad underneath the Distal there And the tip And then you get that Classic kind of Curved up Thumb shape See what makes Now you know what makes the shape Or really the When we talk about the form You know how in the form Now the thumb is made And really all the fingers You can control all of these So there we go here And a little bit of The bottom gets bulky The tip More triangle to follow The distal and the nail Could come out Just a little bit Contouring of that there And there's the end of the bone And the fat pad underneath Like before So we get that kind of Extended thumb And the pinky finger Is more attached back Kind of graceful pose Metacarpal phalangeal joint With the proximal fat pad underneath We'd see a little bit of that Almost covered up Bone Look how arch the bone is in And then fat pad So the fat pad can fit in that groove So that makes sense And then the fat pad Will be for the tip And through that region there We're almost Almost got it Pretty close to Getting all our parts together here And the nail will come out of that That keratin Part of the nail And those can get You can damage your nail I've damaged Those of you know my right hand My thumb Is most of that nail Is about half way Just damaged I put a Sheet rock screw Into it I'm right handed I had to use my left hand For the gun The sheet rock screw gun And for a little tight point It kind of Popped off the wall And then went right into my thumb Luckily didn't get too deep But it kind of damaged the nail The nail never grew back Well And so it comes in All kind of dead looking So I just I cut it back Well I guess you didn't want to know all that But TMI But there you go All right So that's I mean an interesting kind of Biological anatomical thing that happens So I'm going to clean this up a little bit A little further You can see how to do that And of course you could take this Really really cleaned up You could do an ultra tight Finished drawing This would take another hour or two That's not the point here I think we've got all the Anatomical parts From the deltoid To the distal tip That we wanted Deltoid Deltoid shoulder All the way to the distal Fat pad of each Each finger Which does Which serves us really well And we'll just clean up this deltoid So all that We just understand that All this is covering up The humerus The clavicle The scapula The tendons of the coracobrachialis
