L/taste buds (on the tongue, and in smaller quantities in the upper palate, pharynx, and epiglottis)
a defect in which the eye cannot create a sharp focused image on the retina; can be caused by irregular curvature of cornea or lens
a clouding in the lens, leading to partial or complete loss of vision; can be caused by diabetes, hypertension, trauma, chromosomal disorders
acute inflammation of the conjunctiva; generally caused by allergies, but sometimes by viral or bacterial infection
syndrome in which the retina detaches from its support tissue; can be caused by trauma or small tears that allow vitreous fluid to accumulate deep to the retina

the "white" of the eyeball || covers the entire eyeball, except the cornea || C/dense connective tissue
the middle layer of the eyeball || comprised of choroid, ciliary body, and iris
posterior portion of the vascular tunic || highly vascularized; lines most of the internal surface of the sclera
L/the bony labyrinth [superficial layer of the semicircular canals] || C/chemically similar to CSF
L/membranous labyrinth [inner layer of the semicircular canals]
L/vitreous chamber [large cavity between lens and retina] || C/a jellylike substance [unlike aqueous humor, is not constantly replaced] || F/contains phagoctyes that remove debris; holds retina in place
