Cranial Nerves Part 1

About this video

Taught session covering clinical aspects of cranial nerves I, II, III, IV, and VI

Parasympathetic nerves act to constrict the pupil, parasympathetic dysfunction caused by compression of the fibres leads to inhibition of these signals, leading to unopposed pathological dilation.
