Concept Disease

Eyes & Ears

region between the cornea and the lens that contains aqueous humor anterior chamber
fluid produced in the eye aqueous humor
part of the eye that produces aqueous humor ciliary body
layer containing blood vessels that nourish retina choroid
outer, transparent structure that covers the iris, pupil, and anterior chamber cornea
colored ring of tissue behind the cornea that regulates the amount of light entering the eye by adjusting the size of the pupil iris
transparent structure suspended behind the iris that helps to focus light on the retina lens
portion of the retina that processes sharp, clear, "straight-ahead" vision macula
bundle of nerve fibers that carry visual messages from the retina to the brain optic nerve
light enters the eye through this adjustable opening at the center of the iris pupil
light-sensitive layer of tissue that lines the back of the eye retina
tough outer coat that protects the eyeball sclera
clear jelly-like substance that fills the eye from the lens on back vitreous
presence of light, image formed on retina, rod/cones stimulated, nerve impulses to brain & brain interprets image process of vision
an image is formed on the retina
adapt the eye to detect low-intensity light rods
cells in the retina enabling visual detection of color and fine detail cones
during the process of vision nerve impulses are conducted to cranial nerve II
is the key to sight light
light rays travel in a straight line or bend at an angle
process of bending light rays is called refraction
the image formed on the retina is backward & up side down
image is turned right side up and forward in the brain
brain interprets the visual concept
