1. Optic nerve

   The optic nerve, also known as cranial nerve II, or simply as CN II, is a paired cranial nerve that transmits visual information from the retina to the brain. In humans, the optic nerve is derived from optic stalks during the seventh week of development and is composed of retinal ganglion cell axons and glial cells; it extends from the optic disc to the optic chiasma and continues as the optic tract to the lateral geniculate nucleus, pretectal nuclei, and superior colliculus.

1. optic nerve

   The optic nerve is a bundle of more than one million nerve fibers that carry visual messages from the retina, the light-sensing layer of cells at the back of the eye, to the brain. It is part of the central nervous system and can be thought of as the 'cable' connecting the eye to the brain. Damage to the optic nerve can result in vision loss, as the nerve cannot regenerate or repair itself.

1. Optic Nerve

   The 2nd cranial nerve. The optic nerve conveys visual information from the retina to the brain. The nerve carries the axons of the retinal ganglion cells which sort at the optic chiasm and continue via the optic tracts to the brain. The largest projection is to the lateral geniculate nuclei; other important targets include the superior colliculi and the suprachiasmatic nuclei. Though known as the second cranial nerve, it is considered part of the central nervous system.
