Parts of the Eye and Eye Disorders Pretest By: Colby Tharp Parts of the Eye Parts of the Eye Anterior and Posterior Chambers Front Section (anterior segment) Conjunctiva Anterior chamber is between the cornea and the
○ Anterior chamber is between the cornea and the iris ○ Posterior chamber is between the iris and the lens
○ Conjunctiva ○ Cornea ○ Iris ○ Pupil ○ Ciliary body ○ Crystalline lens ○ Aqueous Humor
○ Conjunctiva ■ Thin layer ■ Protection
○ Front of the eye ○ Transparent ○ Rich supply of nerve fibers ○ Sensitive ○ Tears
○ Heavily pigmented ○ Eye color
○ Hole
○ Zonules ○ Increased pressure
○ Biconvex lens ○ Hardening ○ Cloudy
○ Viscous liquid ○ Prevents the eye from collapsing
○ Vitreous Humor ○ Choroid ○ Sclera ○ Optic Nerve ○ Retina ○ Macula ○ Central Retinal Artery ○ Central Retinal Vein
○ Jelly-like material ○ Water, proteins, and collagen ○ Clumps - floaters
○ Thin ○ Nourishment for the retina
○ “White of the eye” ○ Exterior and interior ○ Strong ○ Protection
○ Photoreceptors ○ Natural blind spot
○ Thin multilayer tissue ○ Rods and Cones
○ Central part ○ Sensitive ○ Heavy workload, retinal problems
○ Supplies the retina
○ Main blood vessel ○ Oxygen
○ Clouding of the lens ○ Common
○ Increased fluid pressure ○ Group of conditions
