ANATOMY

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 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.

Detailed explanation-3: -Description. The optic nerve is a bundle of more than 1 million nerve fibers. Also known as the second cranial nerve or cranial nerve II (CNII), it is the second of several pairs of cranial nerves. It transmits sensory information for vision in the form of electrical impulses from the eye to the brain.

Detailed explanation-4: -Cranial nerve II, the optic nerve, controls the special sense of vision. As a direct extension of cerebral tissue, the retina is involved in the reception of photons and transmission of these light signals to the occipital cortex.

Detailed explanation-5: -The optic nerve is the second of 12 cranial nerves. Each eye has its own optic nerve. The optic nerve: Starts in the optic disk, a group of cells in retinal tissue at the back of your eye.
