what is the optic nerve and its function
How Does the Optic Nerve Function? The optic nerve may be found in your eye, but it is part of the central nervous system. The optic nerve takes visual information gathered from your eye and transmits it using a series of electrical impulses to the parts of your brain that act as vision centers, allowing you to make sense of what you are seeing.
Optic nerve. For other uses, see Optic Nerve. The optic nerve, also known as cranial nerve II, is a paired nerve that transmits visual information from the retina to the brain. 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.
Optic Nerve. The Optic Nerve, also called Cranial Nerve II, is the nerve that transmits visual information from the Retina to the Brain. Optic Disc. The Optic Disc or Optic Nerve head is the point in the eye where the optic nerve fibers leave the retina. Due to absence of light sensitive rods and cones of the retina at this point, it is not sensitive to light and thus is also known as The Blind Spot or Anatomical Blind Spot.
