| Question | Answer |
|---|---|
| Anterior chamber | area of the eye in front of the iris that holds the vitreous humor and regulates the pressure in the eye |
| auditory ossicle | bones of the inner ear that transmit sound vibrations |
| cochlea | spiral shaped passages in the inner ear that recieve sound vibrations and initiates an impulse to the brain for translation |
| cones | cells in the eye that allow animals to see colors |
| constrict | to close |
| cornea | clean outer layer of the eye that is commonly easily damaged or scratched |
| dilate | to open |
| dynamic equilibrium | maintaining balance in response to rotational or angular movement |
| ear | sensory organ that enables hearing |
| eustachian tube | narrow duct that leads from middle ear to the nasopharynx and maintains air pressure |
| external auditory canal | tube that transmits sound from the pinna to the tympanic membrane |
| iris | middle layer of the eye that gives the eye it's color and holds the pupil |
| menace response test | a reflext test of the eye where a hand is moved quickly toward the eye without touching the eye or any hair around the eye |

| round window | membrane that receives sound waves through fluid passed through the cochlea |
| sclera | outer white layer of the eye |
| semicircular canals | sensory cells that generate nerve impulses to regulate position |
| static equilibrium | maintenance of the position of the hear relative to gravity |
| tympanic bulla | osseous chamber at the base of the skull |
| tympanic membrane | eardrum, tissue that separates the outer and middle ear |
| vestible | portion of the inner ear that contains specialized receptors for balance and position |
| vitreous humor | jelly like fluid material located behind the iris and lens that controls the pressure of the eye |
