Q

Adapt rapidly, only respond to new stimuli

A

Phasic Receptors

63
utricle saccule are in what?
vestibule
64
Cochlear hair cell stimulation
When basilar membrane moves up, hair cells are pushed into tectorial membrane and their tips are tilted, pulling tip links
65
What does Pitch depend on?
loudness depends on wave amplitude
66
loudness depends on
wave amplitude
67
The saccule and utricle detect both stationary position of the head and linear acceleration of the head.
