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 of the pupil

lens

lies directly behind the pupil; focuses and bends lights

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

eustachian tube

passage between the middle ear and the pharynx; equalizes air pressure on both sides of the tympanic membrane

external auditory canal

short tube ending at the tympanic membrane

outer ear

consists of the auricle and external auditory canal

inner ear

also called labyrinth

middle ear

consists of the tympanic membrane, eustachian tube, and ossicles
