Download Lecture Overview
00:00 The optic nerve like the olfactory nerve has one special functional component and that’s the special afferents. 00:10 As the name implies, this particular nerve is responsible for vision. We can see the optic nerve here as well as here. Clinical considerations associated with the optic nerve is that lesions to the optic nerve may lead to blindness. There may be impairment in some of the visual fields. An individual may lose their ability to constrict their pupil. The optic nerve is involved in the clinical disorder, multiple sclerosis as that leads to demyelination of the optic nerve and visual impairment. Some causes of these clinical considerations. 01:15 A tumor can impair a vision or disrupt vision. Strokes may lead to lesions of the visual pathway. 01:25 Inflammation of the optic nerve can also disturb visual input. That would be termed optic neuritis.

Great job covering the cranial nerve here and it goes well with the visual pathway video
no explanation in this all cn videos plzz elaborate olzz
No explica la anatomia de este nervio, solo estan consideraciones clinicas
It is very superficial. He just repeats whatever appeared on the slides. Additionally, the Doctor makes the lecture very boring.
