The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
The optic nerve (cranial nerve II) is not involved in taste, as its primary function is vision. Taste is primarily mediated by the facial nerve (cranial nerve VII), glossopharyngeal nerve (cranial nerve IX), and vagus nerve (cranial nerve X).
The spinal accessory nerve (cranial nerve XI) is involved in hyperextending and flexing the neck. This nerve innervates the trapezius and sternocleidomastoid muscles, which are involved in these movements.
Trigeminal (5th) cranial nerve
It is the 7th cranial nerve (facial nerve).
The cranial nerves involved in diplopia are the third (oculomotor), fourth (trochlear), and sixth (abducens) cranial nerves, which control eye movement and coordination. Issues with these nerves can result in misalignment of the eyes, leading to double vision.
The Vagus nerve
Cranial nerve 9: glossopharyngeal
Trigeminal neuralgia is a rare disorder of the sensory fibers of the trigeminal nerve (fifth cranial nerve), which innervate the face and jaw. The neuralgia is accompanied by severe, stabbing pains in the jaw or face.
The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
Cranial nerve VIII - vestibulocochlear
The cranial nerve involved in raising the eyelids is the oculomotor nerve (cranial nerve III). For focusing the lens of the eye for accommodation, the oculomotor nerve controls the ciliary muscle.
