and what about the second type?
It is known as cranial nerve II, or simply as CN II, a paired cranial nerve that transmits visual information from the retina to the brain.
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.
where do the cranial nerves branch off the brain The terminal nerves; olfactory nerves and optic nerves emerge from the cerebrum, and the remaining ten pairs arise from the brainstem, which is the lower part of the brain. what do they do? They relay information between the brain and parts of the body. do they have a nucleus? All cranial nerves have a nucleus. With the exception of the olfactory nerve and optic nerve, all the nuclei are present in the brainstem. what is this first type of nerve? It is typically considered the first cranial nerve, or simply CN I, that contains sensory nerve fibers relating to the sense of smell.

Optic nerve [SEP] Introduction
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.
