CRANIAL NERVES Nerve Name Function I. olfactory nerve Sensory nerve for smell from nasal cavity II. optic nerve Sensory nerve for vision from retina III. oculomotor nerve Motor nerve* to 4 of the 6 extrinsic eye muscles Parasympathetic nerve to iris and ciliary muscles IV. trochlear nerve Motor nerve* to 1 of the 6 extrinsic eye muscles V. trigeminal nerve This nerve has three major divisions: V1 Sensory nerve (touch, pain, etc.) from upper third of face ophthalmic division V2 maxillary division Sensory nerve from middle third of face and upper teeth V3 mandibular division Sensory nerve from lower third of face and lower teeth Motor nerve* to muscles of mastication VI. abducens nerve Motor nerve* to 1 of the 6 extrinsic eye muscles VII. facial nerve Sensory nerve from taste buds Motor nerve* to muscles of facial expression Parasympathetic nerves to lacrimal, nasal, and most salivary glands VIII. vestibulocochlear nerve Sensory nerve for hearing and balance from inner ear IX. glossopharyngeal nerve Sensory nerve (touch, pain, etc.) from posterior tongue and pharynx and some taste buds Motor nerve* to muscles involved in swallowing Parasympathetic nerve to one salivary gland X. vagus nerve Sensory nerve from thoracic and abdominal organs Parasympathetic nerve to thoracic and abdominal organs XI. accessory nerve Motor nerve* to muscles of larynx and pharynx, trapezius and sternocleidomastoid muscles XII. hypoglossal nerve Motor nerve* to muscles of tongue *All motor nerves also carry proprioceptive neurons which are sensory neurons.
