100
Part of the ear that funnels sound waves into the auditory canal.
What is the pinna?
100
Thin membrane that vibrates and conducts sound waves through the middle ear.
What is the tympanic membrane?
100
Contains special auditory liquids through which sound waves vibrate.
What is the cochlea?
100
Transparent, biconvex body that refracts light rays to bring them into focus on the retina.
What is the lens?
100
Carries impulses from the retina to the brain.
What is the optic nerve?
200
Part of the ear that funnels sound waves into the auditory canal.
What is the auricle?
200
General term for the small bones in the middle ear that help conduct sound waves.
What are the ossicles?
200
Circular, maze-like structure, also called the inner ear.
What is the labyrinth?
200
Controls the shape of the lens and secretes aqueous humor.
What is the ciliary body?
200
Point at which optic nerve fibers cross in the brain.
What is the optic chiasm?
300
Lubricates and protects the ear canal.
What is cerumen?
300
Separates middle and inner ear.
What is the oval window?
300
Carries sound waves to the cerebral cortex.
What are the auditory nerve fibers?
300
Maintains the shape of the eyeball; located in the posterior chamber.
What is the vitreous humor?
300
Relay center of the brain.
What is the thalamus?
400
Secretes cerumen and leads to the tympanic membrane.
What is the auditory canal/external auditory meatus?
400
Regulates/equalizes pressure in the ear.
What is the eustachian tube?
400
Contains endolymph and sensitive hair cells that fluctuate in response to the movement of the head. Also helps to regulate balance.
What is the semicircular canal?
400
Blind spot of the eye.
What is the optic disc?
400
Produces a single, visual sensation with a three-dimensional effect.
What is the cerebral cortex?
500
General section of the ear that consists of the auricle and auditory canal.
What is the outer ear?
500
The order that the small bones in the ear vibrate to carry sound waves to the inner ear.
What is the malleus, incus, and stapes?
500
Receives vibrations from the auditory liquids and relays sound waves.
What is the Organ of Corti?
500
Supplies nutrients to the eye.
What is the choroid?
500
Section of the optic nerve that carries the impulses after crossing in the optic chiasm.
What is the optic tract?
