Cranial Nerve 2 - Optic Nerve
The olfactory nerve which is also cranial nerve number 1 is responsible for the sense of olfaction.
The cranial nerve responsible for hearing and equilibrium is vestibulocochlear nerve (CN VIII). It originates from between the pons and medulla.
Cranial nerve number 2 is the optic nerve, responsible for most of the sensation of sight.

Trigeminal V: a mixed nerve responsible for the chewing of food and sensations in the face, scalp, and teeth and the contraction of chewing muscles.
The third cranial nerve, the oculomotor is responsible for blinking and most other eyelid movement.
The cranial nerve responsible for moving the cheek muscles is cranial nerve V (the trigeminal nerve). However, cranial nerve IX (glossopharyngeal) and cranial nerve XII (hypoglossal) are also involved in moving the tongue, the throat for swallowing and the muscles along the floor of the jaw.
Trigeminal neuralgia is a rare disorder of the sensory fibers of the trigeminal nerve (fifth cranial nerve), which innervate the face and jaw. The neuralgia is accompanied by severe, stabbing pains in the jaw or face.
Cranial nerve III (CN3) is responsible for keeping the eye open. Cranial nerve VII (CN7) closes the eyelid.
