When taste buds are stimulated they can produce 4 different sensations (sweet, salty, bitter, sour). These nervous impulses are carried to the brain by the facial nerve (cranial nerve VII)from the anterior 2/3 of the tongue and by the glossopharyngeal (cranial nerve IX) from the posterior 1/3 of the tongue.
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 vestibular (VIII)
The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
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).
VII the cranial nerve or the Facial
equilibrium, taste, tears, and tongue movement
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
The Vagus nerve
Cranial nerve 9: glossopharyngeal
The five primary taste qualities are sweet, sour, salty, bitter, and umami. The cranial nerves responsible for taste are the facial nerve (VII), glossopharyngeal nerve (IX), and vagus nerve (X). They carry taste information from the taste buds on the tongue to the brain.
