Term
Mixed nerves, but primarily motor in function. Supply motor fibers to trapezius and sternocleidomastoid muscles, which together move head and neck, and convey proprioceptor impulses from same muscles
a) Vagus (CN X)
b) Hypoglossal (CN XII)
c) Accessory (XI) |

Term
Primarily motor nerves; supply somatic motor fibers to (and carry proprioceptor fibers from) one of the extrinsic eye muscles, the superior oblique muscle, which passes through the pulley-shaped trochlea
a) Oculomotor (CN III)
b) Trigeminal (CN V)
c) Trochlear (CN IV) |

Term
Mixed nerves, but primarily motor in function. Carry somatic motor fibers to intrinsic and extrinsic muscles of tongues, and proprioceptor fibers from same muscles to brain stem. The nerve control allows tongue movements that mix and manipulate food during chewing, and contribute to swallowing and speech.

Term
Mostly Sensory. Vestibular branch transmits afferent impulses for sense of equilibrium, and sensory nerve cell bodies are located in vestibular ganglia. Cochlear branch transmits afferent impulses for sense of hearing, and sensory nerve cell bodies are located in spiral ganglion w/in cochlea
a) Vestibulocochlear (CN VIII)
b) Facial (CN VII)
c) Oculomotor (CN III) |

Term
Somatic motor fibers to 4 of the 6 extrinsic eye muscles that help direct eyeball, and to levator palpebrae superioris muscle, which raises upper eyelid.
Parasympathetic motor fibers to sphincter pupillae which cause pupil to constrict, and ciliary muscle, controlling lens shape for visual focusing
a) Optic (CN II)
b) Oculomotor (CN III)
c) Olfactory (CN I) |
