choroid

middle layer of the eye containing many blood vessels

cornea

transparent anterior part of the sclera that lies over the iris and pupil

Iris

pigmented muscular structure that regulates the amount of light entering the eye by controlling the size of the pupil

lens

lies directly behind the pupil; focuses and bends light

optic nerve

carries visual images from the retina to the brain

pupil

opening through which light passes in the center of the iris

retina

innermost layer of the eye; contains the vision receptors

sclera

outer protective layer of the eye (also called white of the eye)

auricle (pinna)

external, visible part of the ear located on both sides of the head; directs sound waves to the external auditory canal

coiled portion of the inner ear that contains the organ for hearing
