Vagus nerve (Cranial Nerve X)

Trigeminal nerve (Cranial Nerve V)

Optic nerve (Cranial Nerve II)

Verified step by step guidance

Identify the cranial nerve associated with facial movements and expressions. This is crucial because Bell's palsy affects facial muscles.

Recall that the facial nerve is responsible for controlling the muscles of facial expression. It is also known as Cranial Nerve VII.

Understand that Bell's palsy is characterized by sudden weakness or paralysis of the muscles on one side of the face, which is directly linked to the dysfunction of the facial nerve.

Differentiate between the functions of the other cranial nerves listed: the Vagus nerve (Cranial Nerve X) is involved in autonomic control of the heart and digestive tract, the Trigeminal nerve (Cranial Nerve V) is responsible for facial sensation and chewing, and the Optic nerve (Cranial Nerve II) is related to vision.

Conclude that the paralysis seen in Bell's palsy is due to the impairment of the facial nerve (Cranial Nerve VII), as it directly affects facial muscle control.
