Sheep Eye Dissection

 This is a sheep eye. on the outside we have the cornea. eyelid, sclera, optic nerve, and some fatty tissue.

 After cutting the eye in half, we are now able to see the lens, vitreous humor, choroid, tapetum lucidum , retina, and cillary bodies. The lens and vitreous humor are used to help maintain the shape of the eye while the choroid is used to nourish the retina and vitreous humor. The blind spot is the concentrated collection that turns into the optic nerve. The tapetum lucidum helps reflect more light for better night vision.

 This is the cornea and pupil. The cornea protects the delicate portions of the eye while the pupil controls the amount of light that enters the eye.
