Intraocular muscles & nerves (anatomy, pupils and lens)

Since we've spent so much time outside the eyeball we should also see how nerves get inside. The obvious nerve is the optic nerve (CN II) but what about sympathetic and parasympathetic nerves, and general sensory stuff?

Thank you so much. Med school life saver

Excellent tutorial. Thorough and well explained. We had our lecturer reference you as a resource because, "You do a much better job of explaining these things." True MVP for exams. Thank you.

You should have views in millions I mean lots of hard work. Love your work from Pakistan. My sincere thankfulness

That these tissues can be end use specific just incredible. Design of rotation of eye in socket and ability to enervate and blood supply during operating conditions. Auto focus and light sensitive. Add a splash of color for individual unique beauty. Kudos to research and development.

Thanks!

I have enjoyed your videos and learned a lot from them, but where can I find the same level of explanation on the mechanisms and anatomy of the eyelids? there is very little that explains as well as you have on the eyeball mechanics and nerves. I would love to see a very deep dive on eyelid anatomy and how they open and close, the blink response etc...

Where can one buy these models? They appear extremely helpful as supplemental resources to books.

13:40 One of the main ways that sympathetic neurones travel around the body is by following arteries .

[@user-if4df7lk1z]

If the optic nerve is an exention of the brain, is it lined with the meninges? If so, does it have cerebrospinal fluid?

[@ayurved3387]

Plzz upload video on nose anatomy..

[@pointer2null]

So if you have age related long sightedness, does that mean the muscle isn't strong enough to squash the lens or that the ciliary body is fully contracted but the suspense ligaments are now slack and the lens is still thin?

[@stephcaragay]

The cilliary muscles weaken and so the crytalline lens looses its elasticity thus their ability to accomodate (the ability to see at near) lessens.
