Parts of the eye
-attaches the lens to the ciliary body
-fluid in the anterior segment of eye that provides nutrients to the lens and cornea
-the "white" of the eye - protective layer
-area of retina that lacks photoreceptors
-contains muscle that controls the shape of the lens -attaches ciliary zone and iris
-nutritive (vascular) layer of the eye -heavily pigmented layer that prevents light scattering in the eye
-layer containing the rods and cones
-gel-like substance that helps to reinforce the eyeball
smooth muscles structures (2)
-ciliary body & iris
-area of acute or discriminary vision
refractory media of the eye (4)
-cornea -lens -aqueous humor -vitreous humor
most anterior part of the sclera- your "window" to the world
pigmented "diaphgragm" of the eye
what do tarsal glands produce?
what does the conjunctiva produce?
trace the pathway of light from the time it hits the cornea until it excites the rods and cones.
cornea---> aqueous humor---> pupil---> aqueous humor---> lens---> vitreous humor--->retina--->rods/cones
- pink eye -caused by viruses or bacteria
increased pressure in the eyeball due to obstruction of the outflow of aqueous humor
