|
Term
|
Definition
| Primarily motor nerves, controls some extrinsic eye muscles and the superior oblique muscle |
|
|
Term
|
Definition
| Largest cranial nerve, transmits afferent impulses from touch, temperature, pain receptors, contains some motor fibers that innervate chewing muscles |
|
|
Term
|
Definition
| Primarily motor, supplies somatic motor fibers to lateral rectus muscle, an extrinsic eye muscle, and conveys proprioceptor impulses from the same muscle to the brain |
|

Term
| Vestibulocochlear Nerve (VIII) |
|
Definition
| Purely sensory, transmits impulses for sense of equilibrium and sense of hearing |
|
|
Term
| Glossopharyngeal Nerve (IX) |
|
Definition
| Conducts taste and sensory impulses from pharynx and posterior tongue |
|
|
Term
|
Definition
| Most motor fibers are parasympathetic efferents, except those that serve skeletal muscles involved in swallowing. Transmits impulses from thoracic and abdominal viscera, carotid sinus, taste buds in the pharynx, and aortic bodies |

Term
|
Definition
| Mostly motor in function. Supplies motor fibers to larynx, pharynx and soft palate, trapezius and sternocleidomastoid muscles, which move the head and neck |
|
|
Term
|
Definition
| Carries somatic motor fibers to intrinsic and extrinsic muscles of tongue. Allows food mixing and manipulation by the tongue and tongue movements involved in swallowing and speech |
