Neuroma of the Auditory Nerve Anatomy

To better understand acoustic neuroma, it helps to understand the anatomy of the cranial nerves and brain.

Acoustic neuromas arise from Schwann cells, which form a protective covering for nerves. They usually occur in the brain around the eighth cranial nerve. This nerve conducts signals from the inner ear, which senses hearing and balance. The facial nerve (cranial nerve VII) and trigeminal nerve (V) are other common locations for a schwannoma.

Anatomy examples:

  • Cranial nerves
  • Anatomic location of acoustic neuroma
