Nerve Supply
The mandibular and maxillary branches of the trigeminal nerve (CN V) innervate the structures derived from the corresponding processes of the first arch. In some lower animals, each arch is supplied by two cranial nerves.The nerve of the arch itself runs along the cranial side of the arch and is called post-trematic nerve of the arch.Each arch also receives a branch from the nerve of the succeeding arch called the pre-trematic nerve which runs along the caudal border of the arch.In human embryo,a double innervation is seen only in the first pharyngeal arch.The mandibular nerve is the post-trematic nerve of the first arch and chorda tympani (branch of facial nerve) is the pre-trematic nerve.This double innervation is reflected in the nerve supply of anterior two-thirds of tongue which is derived from the first arch.

Famous quotes containing the words nerve and/or supply:
“Tom: All right, boys. C’mon. Why don’t you say I’m a yellow belly and a big mouth at that?
Shep: You yellow? Who thinks you’re yellow? Did you hear what he said? A guy who’s got the nerve to marry? That’s more than Flash Gordon ever did.”
—Billy Wilder (b. 1906)
“Has God’s supply of tolerable husbands
Fallen, in fact, so low?
Or do I always over-value woman
At the expense of man?
Do I?
It might be so.”
—Robert Graves (1895–1985)
