Neuroanatomy Review Part 2- Cranial Nerves

Front

What is the function of CN IX (Glossopharyngeal)?

Back

CN IX is responsible for taste sensation from the posterior one-third of the tongue, sensation from the tonsils, and motor function for swallowing.

Front

What is the primary role of CN XII (Hypoglossal)?

Back

CN XII controls the motor movement of the tongue, essential for speech and swallowing.

Front

Which cranial nerve innervates the larynx?

Back

CN X (Vagus) is responsible for innervating the larynx.

Front

Where are Upper Motor Neurons located?

Back

Upper Motor Neurons are located in the cerebral cortex.

Front

What branch of the Vagus nerve supplies the larynx?

Back

The Recurrent laryngeal nerve supplies the larynx.

Front

What are the main functions of the Vagus nerve (CN X)?

Back

The Vagus nerve controls heart rate, gastrointestinal peristalsis, sweating, and several muscle movements in the voice box.

Front

What is the sensory function of CN V (Trigeminal)?

Back

CN V provides sensation to the face, including touch, pain, and temperature.

Front

What is the role of CN VII (Facial) in taste?

Back

CN VII is responsible for taste sensation from the anterior two-thirds of the tongue.

Front

What is the function of the Recurrent laryngeal nerve?

Back

The Recurrent laryngeal nerve innervates the muscles of the larynx, except for the cricothyroid muscle.

Front

What symptoms might indicate damage to CN IX (Glossopharyngeal)?

Back

Symptoms may include loss of gag reflex, difficulty swallowing, and loss of taste in the posterior tongue.
