Cranial Nerves III, IV & VI Explained - What do they do and how to examine them - Dr James Gill

The ultimate guide to the cranial nerves continues with a triple features cranial nerve III, IV and VI are all examined at the same time, as these nerves control how the eyes move

Over this series of videos I'll be covering what most people have asked for, additional information on

- The normal function of each cranial nerve
- How / why any special tests are performed
- crucially what is being looked at during each step of the examination.

I'm hoping to have this whole series finished this week - it was previously going to be delivered as a single video, but I think it would be more useful for people to be able to jump in and out to the various nerves they are wanting extra information on

Keep dropping the comments, and I'm really grateful for all the improvements people are suggesting, which is helping this channel to evolve - THANK YOU
