Answer
The difference between hearing and equillibrium is :
- One is stimulated by fluid movement in cochlea, and the other is stimulatted by movements in the vestibular apparatus.
- Inner ear consist of cochlea and vestibular apparatus.
- Cochlea contains organ of corti with mechanoreceptors for sense
of hearing. It sends impulse via cochlear branch of
vestibulocochlear nerve.
- Vesticular apparatus (semicircular canals, utricle and saccule)
contains mechanoreceptors for sense of equillibrium / balance. It
sends impulse via vestibular branch of vestibulocochlear nerve.
Option B
Add Answer to:
Which is a difference between hearing and equilibrium? One uses the vestibulocochlear nerve, and the other...
