Aqueous humor

clear watery fluid fills space between cornea and iris, curvature of eyeball and refracts light rays

Auditory Canal

Tube where sound waves travel through to tympanic membrane

Auricle

outter ear

Choroid coat

middle layer of the eye, many blood vessels to nourish eye

Cochlea

snail's shell structure with many delicate hairs

Conjunctiva

mucous membrane of the eye lids and front of the eye, protection and lubrication

Cornea

circular transparent front part of sclera, allows light rays to enter eye

Eustachian tube

allows air to enter middle ear, equalize pressure on both sides of the tympanic membrane

Iris

colored part of the eye, located behind cornea and in front of the choroid coat

Lacrimal glands

produce tears, moisten and clean the eye

Lens

circular structure located behind the pupil suspended by ligaments

Organ of Corti

receptor of sound waves to the auditory nerve, carries impulses to temporal lobe of the cerebrum...hearing

Ossicles

3 small bones MALLEUS, INCUS, STAPLES connected and transmit sound

Pinna

or Auricle,

outter ear

Pupil

opening in the center of the iris, 2 muscles thast control and regulate amount of light entering

Refracts

bends light rays

Retina

inner most layer of the eye/nerve cells, transmits light impulse to the optic nerve

Sclera

outermost tough connective layer of the eye maintains the shape extrinsic muscles move the eye within the socket (white)

Semicircular canals

located in inner ear canals contain liquid and delicate hair like cells that bend when the liquid moves in the head. balance and equalibrium

Tympanic membrane

separates outter from middle ear, vibrate and transmits the sound wave to the middle ear

Vestibule

1st section of oval window

Vitreous humor

jellylike substance behind lens, shape and refraction
