7 there is one nerve per eye connecting each eye to the brain. Innervation of the eyeball and surrounding structures is provided by the optic, oculomotor, trochlear, abducens and trigeminal cranial nerves. It carries impulses for sight from the retina to the brain.

It Carries Impulses For Sight From The Retina To The Brain.


The optic nerve is the largest sensory nerve of the eye. The optic nerve is located at the very back of the eye, attached to the retina. This retina is the only part of the eye that perceives the light and converts it into electrical energy.

The Optic Nerve Is A Bundle Of About 1.2 Million Nerve Fibers That Transmit Visual Information To The Central Nervous System (Brain).


This neural coat of the eye is an essential part of the eye. The iris adjusts the size of the pupil and controls the amount of light that can enter the eye. Starts in the optic disk, a group of cells in retinal tissue at the back of your eye.

Controls All Of The Extraocular Eye Muscles, Except The Trochlearis And The Lateral Rectus Muscles;


Trochlear nerve (cn iv) inferior oblique. The ophthalmic nerve supplies sensory innervation to the structures of the eye, including the cornea, ciliary body, lacrimal gland, and conjunctiva. The six cranial nerves are the optic nerve (cn ii), oculomotor nerve (cn iii), trochlear nerve (cn iv), trigeminal nerve (cn v), abducens nerve (cn vi), and facial nerve (cn vii).

Each Bony Orbit Accommodates And Protects The Eye And Adnexa, And Serves To Transmit The Nerves And Vessels That Supply The Face Around The Orbit.


Because of its function, the optic nerve is considered part of the nervous system, even though it's located in the eye. The pupil is the opening at the center of the iris. The cranial nerves that control the eye include the optic nerve, the oculomotor nerve, the trochlear nerve and the abducens nerve

The Brain Also Plays A Vital Role In The Focused Image On The Eye's Retina Which Is Actually Upside Down, So That The Brain Cracks.


The six cranial nerves are the optic nerve (cn ii), oculomotor nerve (cn iii), trochlear nerve (cn iv), trigeminal nerve (cn v), abducens nerve (cn vi), and facial nerve (cn vii). Innervation of the eyeball and surrounding structures is provided by the optic, oculomotor, trochlear, abducens and trigeminal cranial nerves. In fact, the only other organ that's more complex than is the brain.
