Question

A patient is diagnosed with an acoustic neuroma. Which cranial nerve (CN) is affected by an acoustic neuroma?

a) Cranial Nerve III
b) Cranial Nerve V
c) Cranial Nerve VII
d) Cranial Nerve VIII

Answer 1

The vestibulocochlear nerve, which is Cranial Nerve VIII, is affected in a patient with an acoustic neuroma, and it is responsible for hearing and balance.

Step-by-step explanation:

A patient diagnosed with an acoustic neuroma is affected in the vestibulocochlear nerve, which is Cranial Nerve VIII. This nerve is responsible for equilibrium and hearing, and an acoustic neuroma is a benign tumor that develops on the nerve. Cranial nerves play crucial roles in the sensory and motor functions of the head and neck. While the optic nerve (CN II) and facial nerve (CN VII) provide important functions like vision and facial expressions, respectively, it is the vestibulocochlear nerve (CN VIII) that carries auditory information to the brain, involved in hearing and balance.
