pinna

collects and funnels sound

tympanic membrane

The eardrum. A structure that separates the outer ear from the middle ear and vibrates in response to sound waves.

eustachian tube

narrow tubes that lead from the middle ear to the nasal cavity and the throat

Incus

A tiny bone that passes vibrations from the malleus to the stapes

Malleus

A tiny bone that passes vibrations from the eardrum to the incus

stapes

A tiny U shaped bone that passes vibrations from the incus to the cochlea.

oval window

membrane at the enterance to the cochlea through which the ossicles transmit vibrations

cochlear duct

a fluid filled cavity within the cochlea that vibrates when sound waves strike it

semicircular canals

three canals within the inner ear that contain specialized receptor cells that generate nerve impulses with body movement

cochlea

A coiled, bony, fluid-filled tube in the inner ear through which sound waves trigger nerve impulses

Conjunctiva

The membrane that covers the front of the eye and lines the inside of the eyelids.

Lacrimal Gland

secretes tears, and is situated laterally and superiorly to the eye —called also tear gland.

Sclera

The white outer layer of the eyeball. At the front of the eye it is continuous with the cornea.

Cornea

The transparent layer forming the front of the eye.

Choroid

Resembling the chorion, particularly in containing many blood vessels.

Pupil

Retina

A layer at the back of the eyeball containing cells that are sensitive to light

Photoreceptors

A structure in a living organism, especially a sensory cell or sense organ, that responds to light falling on it.--rods& cones

Optic Nerve

transmitts impulses to the brain from the retina at the back of the eye.

Optic disc

The raised disk on the retina at the point of entry of the optic nerve, lacking visual receptors and so creating a blind spot.

Fovea Centralis

A small depression in the retina of the eye where visual acuity is highest. The center of the field of vision is focused in this region, where retinal cones are particularly concentrated.

Color Blindness

An abnormal condition characterized by the inability to clearly distinguish different colors of the spectrum. The difficulties can be mild to severe.

Cataracts

A medical condition in which the lens of the eye becomes progressively opaque, resulting in blurred vision.

Vitreous Humor

The transparent jellylike tissue filling the eyeball behind the lens.

Aqueous Humor

The clear fluid filling the space in the front of the eyeball between the lens and the cornea.

Optic Chiasma

The X-shaped structure formed at the point below the brain where the two optic nerves cross over each other.
