◉ sclera.
Answer: eye whites; posterior fibrous outer part of eye
◉ cornea.
Answer: transparent fibrous outer layer of eye on the anterior side (clear
dome)
◉ aqueous humor.
Answer: fluid that fills the eye between the cornea and the lens
◉ choroid.
Answer: dark posterior middle layer of the eye (deeper than sclera);
prevents light dispersal through the eye. Very vascular.
◉ ciliary body.
Answer: ring of tissue surrounding the iris/lens that changes the shape of
the lens so it can focus; secretes aqueous humor
◉ iris.
,Answer: anterior to ciliary body; gives the eye its "color" and controls
the amount of light that enters the pupil
◉ pupil.
Answer: hole in the center of the iris that allows light to enter the eye
◉ fibrous tunic.
Answer: outer layer of the eye
◉ vascular tunic.
Answer: middle layer of the eye; choroid, ciliary body, iris
◉ nervous tunic.
Answer: inner layer of the eye - retina
◉ retina.
Answer: layer of tissue lining the inside of the eye, receives light and
converts it to neural signals; full of photoreceptors
◉ photoreceptors.
Answer: special sensory cells that are sensitive to light
◉ rods.
, Answer: photoreceptors that detect black, white, and gray (intensity of
light); more numerous of the photoreceptors. more active in dim light-
more sensitive but less clear
◉ cones.
Answer: photoreceptors that detect color and operate in brightness.
produce sharp color image
◉ lens.
Answer: part of eye that focuses an image on the retina; posterior to
pupil and iris, suspended by ciliary body
◉ vitreous body.
Answer: the cavity between the retina and the back of the lens; posterior
cavity
◉ vitreous fluid (humor).
Answer: gelatinous liquid that holds retina to choroid and holds lens in
suspension
◉ optic nerve.
Answer: sensory nerve carrying neural impulses (image info) to the
brain from the eye
◉ optic chiasm.
