basilar membrane Flashcards
1
Q
more of the basilar membrane is stimulated by…
A
LOW frequency sounds
2
Q
basilar membrane and the auditory nerve are..
A
tonotopically organized
inside = low freq outside = high freq
3
Q
superior olivary complex
A
1st spot where both ears are represented (stereo effect)
- fibers decussate (cross over) to contralateral side
- nerve travels up and eventually into the auditory cortex
4
Q
all fibers terminate at…
A
the cochlea nucleus
5
Q
basilar membrane function
A
where the cochlea begins analysis of both frequency and intensity of sound signals
6
Q
inner vs outer hair cells
A
far fewer inner, but 90% are neurologically connected to brain via nerve fibers
