Face, nose, and mouth sensations, as well as mastication (or chewing), are controlled by the trigeminal nerve.

The facial nerve is associated with taste, facial expression, and production of tears and saliva. Sensation and swallowing in the pharynx are controlled by the glossopharyngeal nerve. The vagus nerve supplies the pharynx, larynx, and the viscera of the thorax and abdomen. Eye movement is controlled by the trochlear nerve. 

The vagus nerve supplies the viscera of the thorax and abdomen, including the liver, stomach, kidneys, and lungs. The accessory nerve is a motor nerve supplying the neck muscles, pharynx, and larynx. Eye movement is controlled by the abducens nerve. The trigeminal nerve is responsible for face, nose, and mouth sensations and for chewing. Eye movement is controlled by the trochlear nerve.

CN XI only has motor function (innervation of the trapezius and sternocleidomastoid muscles). The other nerves listed have the following parasympathetic functions: pupil constriction (CN III), salivation (CN VII and CN IX) and parasympathetic modulation over multiple internal organs (CN X).

CN XI (accessory nerve) is responsible for head turning and shoulder shrugging via its innervation of sternocleidomastoid and trapezius muscles. CN I (olfactory) is involved in olfaction. CN VI (abducens) allows for eye movement via its innervation of lateral rectus. CN VIII (vestibulocochlear) functions in hearing and balance. CN XII (hypoglossal) is responsible for tongue movement.

Cranial nerve (CN) VIII is the vestibulocochlear nerve. It is purely sensory in function, and is involved in audition, and proprioception. CN VII is the facial nerve. CN X is the vagus nerve. CN II is the optic nerve. 

The vagus nerve (cranial nerve X) innervates the larynx, and is involve in speech production. The accessory nerve innervates the muscles in the neck and upper back. Cranial nerve IX is the glossopharyngeal nerve and innervates the pharynx. Cranial nerve XIII is the hypoglossal nerve that innervates the tongue. 

Cranial nerve III is the oculomotor nerve, which controls most of the muscles needed for eye movement. Also, this nerve controls the ciliary muscle and is responsible for pupillary constriction via parasympathetic innervation. The cranial nerve that makes the eye look to the side is the abducens nerve or cranial nerve VI. The muscle that helps roate the eye down and out is the trochlear nerve or cranial nerve IV. The nerve that carries visual information from the back of the eyeballs to the brain is the optic nerve or cranial nerve II.

The inferior alveolar nerve passes through the mandibular foramen. It has motor and sensory components. It serves to give the lower face and jaw sensation and is also responsible for stimulating the muscles for movement of the jaw.

The trigeminal nerve (cranial nerve V) is responsible for facial sensation and motor functions, such as biting and chewing. The trigeminal nerve has three major branches (hence: tri-): the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3). The opthalmic and maxillary nerves are purely sensory, and the mandibular nerve has both sensory and motor functions. VI provides sensation to the forehead, upper eyelids, and the bridge and tip of the nose. V2 provides sensation lateral to the eyelids, the cheeks, nostrils, and upper lip. V3 provides sensation to the lower lip, chin, skin over the jaw, and pre-auricular area.

Cranial nerves VII and IX supply taste sensation to the tongue. Cranal nerve VII (facial) supplies taste to the anterior two-thirds of the tongue and cranial nerve IX (glossopharyngeal) supplies somatosensation and taste to the posterior one-third of the tongue.
