Cranial Nerves and Their Functions ish

The cranial sensory nerve for smell

• Occulomoter III

• Olfactory I

• Optic II

• Trochlear IV

Cranial sensory nerve for vision

• Optic II

• Occulomoter III

• Trochlear IV

• Abducens VI

Cranial sensory nerve that supplies four of the six extrinsic eye muscles that allow the eyeball to orbit

• Oculomotor III

• Optic II

• Olfactory I

• Hypoglossal

Cranial sensory nerve that innervates an extrinsic eye muscle that loops through a pulley-shaped ligament in the orbit

• Trochlear IV

• Oculomotor III

• Optic II

• Trigeminal V

Cranial sensory nerve that three branches spring from. The largest cranial nerve. It supplies sensory fibers to the face and motor fibers to the chewing muscles

• Trigeminal V

• Vagus X

• Glossopharyngeal IX

• Facial nerve VII

This nerve controls the extrinsic eye muscle that abducts the eyeball (turns it laterally)

• Optic II

• Abducens VI

• Trochlear IV

• Oculomotor III

A large nerve that innervates muscles of facial expression (among other things)

• Vagus X

• Trigeminal V

• Optic nerve II

• Facial VII

This mostly sensory nerve for hearing and balance was formerly called the auditory nerve

• trigeminal V

• vestibulocochlear VIII

• facial VII

• vagus X

The name of this nerve means tongue and pharynx, the structures that this nerve helps to innervate.

• Vagus X

• Hypoglossal XII

• Trigeminal V

• Glossopharyngeal IX

This nerve's name means "wanderer" or "vagabond" and it is the only cranial nerve to extend beyond the head and neck to the thorax and abdomen.

• Trigeminal V

• Accessory XI

• Hypoglossal XII

• Vagus X
