CN VI (Six)

Abducens nerve: Controls another muscle that's associated with eye movement, called the lateral rectus muscle. This muscle is involved in outward eye movement.

CN VII (Seven)

Facial nerve: Provides both sensory and motor functions, including: - Moving muscles used for facial expressions as well as some muscles in your jaw -Providing a sense of taste for most of your tongue - Supplying glands in your head or neck area, such as salivary glands and tear-producing glands - Communicating sensations from the outer parts of your ear

CN XI (Eleven)

Spinal accessory nerve: A motor nerve that controls the muscles in your neck. These muscles allow you to rotate, flex, and extend your neck and shoulders. It's divided into two parts: spinal and cranial.

CN V (Five)

Trigeminal nerve: The largest of your cranial nerves and has both sensory and motor functions. Has three divisions, which are: - Ophthalmic. The ophthalmic division sends sensory information from the upper part of your face, including your forehead, scalp, and upper eyelids. - Maxillary. This division communicates sensory information from the middle part of your face, including your cheeks, upper lip, and nasal cavity. - Mandibular. The mandibular division has both a sensory and a motor function. It sends sensory information from your ears, lower lip, and chin. It also controls the movement of muscles within your jaw and ear.

CN IV (Four)

Trochlear nerve: Controls your superior oblique muscle. This is the muscle that's responsible for downward, outward, and inward eye movements.

CN X (Ten)

Vagus nerve: A very diverse nerve. It has both sensory and motor functions, including: - Communicating sensation information from your ear canal and parts of your throat - Sending sensory information from organs in your chest and trunk, such as your heart and intestines - Allowing motor control of muscles in your throat - Stimulating the muscles of organs in your chest and trunk, including those that move food through your digestive tract (peristalsis) - Providing a sense of taste near the root of your tongue

CN IX (Nine)

Glossopharyngeal nerve: Has both motor and sensory functions, including - -Sending sensory information from your sinuses, the back of your throat, parts of your inner ear, and the back part of your tongue - Providing a sense of taste for the back part of your tongue - Stimulating voluntary movement of a muscle in the back of your throat called the stylopharyngeus

CN XII (Twelve)

Hypoglossal nerve: The 12th cranial nerve which is responsible for the movement of most of the muscles in your tongue. It starts in the medulla oblongata and moves down into the jaw, where it reaches the tongue.

CN III (Three)

Oculomotor nerve: Has two different motor functions - eye muscle function and pupil response.

CN II (Two)

Optic nerve: The sensory nerve that involves vision.

CN VIII (Eight)

Vestibulocochlear nerve: has sensory functions involving hearing and balance. It consists of two parts, the cochlear portion and vestibular portion
