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 |
nystagmus |
condition where the eyes jump back and forth in rhythmic jerks due to damage in the inner ear, brain stem, or cranial nerves |
oval window |
membrane that separates the middle and inner ear |
pinna |
external portion of the ear |
posterior chamber |
area behind the eye that holds the nerves |
pupil |
area in the center of the eye the opens and closes with light response |
pupillary light response test |
light shown into the animal's eyes to note constriction or shrinking of the pupil and dilation or expanding when the light source is removed from the eye |
retina |
inner layer of the eye that contains two types of cells that aid in seeing color and depth |
rods |
cells that allow the eye to detect light and depth and make up 95% of the cells within 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 |
