Cranial Nerve Classification Flashcards

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.
