*the 5th cranial nerve*
(or simply CN V)
.
(the trigeminal nerve is a ‘nerve’ responsible for ‘sensation’ in the face and motor functions such as biting and chewing; it is the largest of the ‘cranial nerves’)
(its name (“trigeminal” = tri-, or three, and – geminus, or twin: thrice-twinned) derives from the fact that each of the two nerves (one on each side of the pons) has three major branches: the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3))
(the ophthalmic and maxillary nerves are purely sensory, where the mandibular nerve supplies motor as well as sensory (or “cutaneous”) functions)
(the motor division of the trigeminal nerve derives from the basal plate of the embryonic pons, and the sensory division originates in the cranial neural crest)
.
(‘sensory information’ from the ‘face’ + ‘body’ is processed by ‘parallel pathways’ in the “central nervous system”)
