parts of the eye and their functions

what is the part of the eye that is the area of the eye that separates the cornea from the iris

• vitreous humor

• anterior chamber

• cornea

• fovea

the clear, jelly-like fluid found in the back portion of the eye: maintains shape of the eye

• cornea

• cones

• vitreous humor

• rods

the small area of the retina where the optic nerve leaves the eye: any image falling here will not be seen

• iris

• blind spot

• pupil

• sclera

the thin muscles that change the lens shape to allow focusing images of objects at different distances

• fovea

• iris

• cones

• ciliary body

transparent tissue covering the front of the eye where light first enters the eye; does not have blood vessels; does have nerves

• cornea

• fovea

• optic nerve

• cones

photoreceptors responsive to color and in bright conditions; used for fine detail

• rods

• fovea

• cones

• iris

photoreceptors responsive in low light conditions; not useful for fine detail

• rods

• cones

• optic nerve

• retina

central part of the macula that provides sharpest vision; contains only cones

• rods

• fovea

• cones

• sclera

circular band of muscles that controls the size of the pupil. The pigmentation of the iris gives "color" to the eye. Blue eyes have the least amount of pigment; brown eyes have the most

• cornea

• lens

• iris

• fovea

transparent tissue that bends light passing through the eye: to focus light, the BLANK can change shape

• fovea

• lens

• iris

• blind spot
