Question

Damage to which cranial nerve (CN) would lead to facial paralysis in the patient?

a) CN III (Oculomotor)
b) CN V (Trigeminal)
c) CN VII (Facial)
d) CN XII (Hypoglossal)

Answer 1

The facial nerve (CN VII) is responsible for facial paralysis in a patient.

Step-by-step explanation:

The cranial nerve responsible for facial paralysis in a patient is the facial nerve (CN VII).

The facial nerve controls the muscles of facial expression and also supplies taste to the anterior two-thirds of the tongue. Damage to the facial nerve can result in facial drooping and difficulty with facial movements, such as closing the eyes, smiling, or frowning.
