optic
The optic nerve, or cranial nerve II, is responsible for visual functioning and carries visual information from the eyes to the brain.
Each eye has one nerve for vision, the optic nerve, Cranial Nerve II. Nerves are actually bundles of many nerve fibers. There are nerves that supply impulses for the muscles associated with the eyeballs so they can move are the Cranial Nerve III, Oculomotor, Cranial Nerve IV, Trochlear, and Cranial Nerve VI, the Abducens nerve.
The third cranial nerve, the oculomotor is responsible for blinking and most other eyelid movement.
The oculomotor nerve or the third cranial nerve, trochlear or forth cranial nerve and abducent or the sixth cranial nerve carry signal to your eye. The optic nerve carry the signal from the eye to the brain. Vestibulocochlear or the eighth cranial nerve carry the signal from your ear to the brain.
cranial nerve I: olfactory:smell cranial nerve II:optic:vision cranial nerve III: oculomotor: 4 of 6 eye muscles cranial nerve IV: trochlear: cranial nerve V: Trigeminal cranial nerve VI: Abducens cranial nerve VII: Facial cranial nerve VIII: Vestibulochlear: hearing cranial nerve IX: Grosspharnxgeal: saliva formation cranial nerve X: Vegus cranial nerve XI: Acessory Spinal: trapizious movement cranial nerve XII: Hypoglosseal: toungue movement
The nerve that supply the motor function of the eyeballs are the occulomotor nerve (cranial nerve III), trochlear nerve (cranial nerve IV) and the abducen nerve (cranial nerve VI). All the muscle that move the eyeballs supplied by the occulomotor nerve except the lateral rectus of the eyes which is supplied by the abducen nerve and the superior oblique muscle of the eyes which is supplied by the trochlear nerve.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
The main nerve required would be the optic nerve (II), although you would also use the ocular motor nerve (III) to move the eyes. Other cranial nerves involved are: Trochlear nerve (IV) and Abducens nerve (VI).
There is one optic nerve in the eye. It is also known as cranial nerve II.
Opening the eyes involves the cranial nerve called the oculomotor nerve (CN III). This nerve innervates the muscles responsible for raising the upper eyelid and controlling the pupil size.
The cranial nerve associated with the eye is the oculomotor nerve (Cranial Nerve III). Damage to this nerve can result in symptoms such as ptosis (drooping of the eyelid), strabismus (misalignment of the eyes), and difficulties in eye movements, leading to double vision. Additionally, it can affect pupil constriction, resulting in a dilated pupil that does not respond to light.
