Question | Answer |
A structure that changes a stimulus into an electrical signal | sensory neuron |
With which part of a neuron are sensory receptors most commonly associated? | dendrites |
How are stimuli of greater intensity encoded? | greater frequency of action potentials |
anterior clear portion of fibrous tunic | cornea |
retinal area providing keenest vision | fovea centralis |
attaches lens to ciliary body | suspensory ligament |
biconvex structure that focuses light | lens |
posterior portion of fibrous tunic | sclera |
mucous membrane covering sclera, lining eyelids | conjunctiva |
"white" of the eye | sclera |
choroid, ciliary body, and iris | vascular tunic |
regulates the amount of light entering the eye | iris |
controls shape of lens for focusing | ciliary body |
tough outer layer, protects, gives shape to eye | sclera |
colored part of eye | iris |
rods & cones are located here | retina |
also known as the "blind spot" | optic disk |
opening in iris allowing light into the eye | pupil |
structures of outer ear | auricle & external acoustic meatus |
structures of the middle ear | malleus, stapes, incus, tympanic membrane, auditory (eustachian) tube |
structures of inner ear | oval window, inner ear, cochlea, semi-circular canals, vestibule, round window |
eardrum | tympanic membrane |
leads sound waves to the eardrum | external acoustic meatus |
equalizes pressure within middle ear | auditory (eustachian) tube |
ossicle in contract with eardrum | malleus |
ossicle in contact with oval window | stapes |
3 auditory ossicles | malleus, incus, stapes |
location of sound receptors | cochlea |
location of equilibrium receptors | vestibule, semicircular canals |
conducts sound waves into inner ear | auricle |
pressure damper for inner ear | round window |
