Cranial Nerve Classification Flashcards

Study Notes

Cranial Nerve Classifications

The olfactory (I) nerve is a sensory nerve involved in the sense of smell.
The optic (II) nerve is a sensory nerve responsible for vision.
The oculomotor (III) nerve is a motor nerve that controls eye movement and pupil response.
The trochlear (IV) nerve is a motor nerve that innervates the superior oblique muscle of the eye.
The trigeminal (V) nerve is a mixed nerve with sensory functions for the face and motor functions for mastication.
The abducens (VI) nerve is a motor nerve that controls the lateral rectus muscle of the eye, enabling lateral eye movement.
The facial (VII) nerve is a mixed nerve that facilitates facial expression and conveys taste sensations.
The vestibulocochlear (VIII) nerve is a sensory nerve that aids in hearing and balance.
The glossopharyngeal (IX) nerve is a mixed nerve involved in taste, swallowing, and salivary gland function.
The vagus (X) nerve is a mixed nerve that regulates autonomous functions of the heart, lungs, and digestive tract.
The accessory (XI) nerve is a motor nerve that controls neck and shoulder movements.
The hypoglossal nerve is a motor nerve crucial for tongue movements.

Nerve Locations by Brain Region

Midbrain contains the oculomotor (III) and trochlear (IV) nerves.
Cerebellum is associated with the olfactory (I) and optic (II) nerves.
Medulla oblongata houses the vagus (X), hypoglossal, accessory (XI), and glossopharyngeal (IX) nerves.
Pons consists of the abducens (VI), facial (VII), vestibulocochlear (VIII), and trigeminal (V) nerves.
