Spiral ganglion processes travel to the _________ nuclei of the medulla by way of cranial nerve _________.
A) cochlear;VIII
B) vestibular;VIII

Question

Quizplus · Accepted Answer

Spiral ganglion processes, which are involved in hearing, travel to the cochlear nuclei of the medulla by way of the cranial nerve VIII, also known as the vestibulocochlear nerve. Therefore, option A is the correct answer. The vestibular nuclei, which are involved in balance and spatial orientation, are also located in the medulla, but they receive input from the vestibular branch of the VIII nerve. Option B and D are incorrect because they refer to the vestibular branch rather than the cochlear branch of the VIII nerve. Option C is also incorrect because cranial nerve VII, also known as the facial nerve, is not involved in hearing.
