Detailed explanation-1: -The mandibular nerve is the only branch of the trigeminal nerve with a motor component (V3). This branch supplies motor innervation to the facial muscles involved in mastication, which include the masseter, temporalis muscle, and lateral and medial pterygoids.

Detailed explanation-2: -Trigeminal neuralgia is severe facial pain due to malfunction of the 5th cranial nerve (trigeminal nerve). This nerve carries sensory information from the face to the brain and controls the muscles involved in chewing. The cause is usually an abnormally positioned artery that compresses the trigeminal nerve.

Detailed explanation-3: -The nerves are: the olfactory nerve (I), the optic nerve (II), oculomotor nerve (III), trochlear nerve (IV), trigeminal nerve (V), abducens nerve (VI), facial nerve (VII), vestibulocochlear nerve (VIII), glossopharyngeal nerve (IX), vagus nerve (X), accessory nerve (XI), and the hypoglossal nerve (XII).
