Two parts of vestibuolocochlear nerve and what they do?
1) vestibular= sense of motion, balabce, acceleration | 2) cochlear= hearing apparatus
79
cochlear nerve is composed of?
central processes of bipolar neurons in the spiral ganglia; the peripheral processes of the neurons extend to the spiral organ for the sense of hearing
80
vestibular nerve is made of?
central processes of bipolar neurons in the vestibular ganglion. the peripheral processes of the neurons extand to the maculae of the utricle and saccule and to the cristae of ampullae of the semicicrcular sucts. the vestibular nerve controls equilibrium and balance.
