WebAcoustic neuroma is a rare non-cancerous tumor. It grows slowly from an overproduction of Schwann cells. The tumor then presses on the hearing and balance nerves in the inner ear. Schwann cells normally wrap around and support nerve fibers. A large tumor can press on the facial nerve or brain structures. WebThe vestibulocochlear nerve is responsible for the sense of hearing and balance (body position sense). Vestibular Schwannoma: IX: glossopharyngeal: The glossopharyngeal nerve enervates muscles involved in swallowing and taste.

The vestibulocochlear nerve consists mostly of bipolar neurons and splits into two large divisions: the cochlear nerve and the vestibular nerve. Cranial nerve 8, the vestibulocochlear nerve, goes to the middle portion of the brainstem called the pons (which then is largely composed of fibers going to the cerebellum). The 8th cranial nerve runs between the base of the pons and medulla oblongata (the lower portion of the brainstem). This ju… WebYou have two main types of nerves: Sensory nerves carry signals to your brain to help you touch, taste, smell and see.
