Hint The optic nerves carry all the nerve impulses from the retina to the human brain for perception. So, the optic nerve is situated at that part of the eye from which it can easily connect to the brain.
Complete answer:
The optic nerve is found within the back of the eye. It's also called the second cranial nerve or nerve II. it's the second of several pairs of cranial nerves. The work of the optic nerve is to transfer visual information from the retina to the vision centres of the brain via electrical impulses.
Additional Information:
The human eye is known to be a sensory organ that responds to light and enables vision. within the retina, rod and cone cells allow the conscious perception of light and vision, including colour differentiation and depth perception.
The optic nerve is formed of ganglionic cells or nerve cells. It consists of over a million nerve fibres. Our blind spot is caused by the absence of specialised photosensitive (light-sensitive) cells, or photoreceptors, within the part of the retina where the optic nerve exits the eye.
Glaucoma is one of the foremost common illnesses affecting the optic nerve. Glaucoma is caused by high pressure, or high within the fluid that's inside the eye (vitreous fluid). This high compresses the optic nerve and causes cells to die. It's mentioned as atrophy of the nervus opticus.
Although the optic nerve is a component of the attention, it's considered a part of the central nervous system.
Note:
The sclera is a part of the eye commonly referred to as the “white.” It forms the supporting wall of the eyeball and is continuous with the clear cornea. The sclera is covered by the conjunctiva, a transparent mucus membrane that helps lubricate the eye. it's thickest within the area surrounding the optic nerve.
