The optic nerve, also known as cranial nerve 2, transmits visual information from the retina to the brain. Derived from the embryonic retinal ganglion cell, a diverticulum located in the diencephalon, the optic nerve does not regenerate after transection.
Famous quotes containing the word nerve:
“our nerve filaments twitch with its presence
day and night,
nothing we say has not the husky phlegm of it in the saying,
nothing we do has the quickness, the sureness,
the deep intelligence living at peace would have.”
—Denise Levertov (b. 1923)
