Detailed explanation-1: -In neuroanatomy, the optic nerve, also known as the second cranial nerve, cranial nerve II, or simply CN II, is a paired cranial nerve that transmits visual information from the retina to the brain.

Detailed explanation-2: -The optic tract is the intracranial continuation of the optic nerve. Like CN II, the optic tract is paired. Each is made up from temporal fibers arising from the retina of the ipsilateral eye, as well as nasal fibers originating from the retina of the contralateral eye.

Detailed explanation-3: -The optic nerve is the second cranial nerve (CN II) responsible for transmitting visual information. The optic nerve contains only afferent (sensory) fibers, and like all cranial nerves is paired.
