Neuroscience Quiz: Nervous System Functions

The trigeminal nerve (cranial nerve V) is responsible for sensory information from the face, including touch, temperature, and pain. It also controls the muscles involved in chewing.

The facial nerve (cranial nerve VII) controls facial expressions, taste sensation on the front of the tongue, and tear and saliva production.

The auditory nerve (cranial nerve VIII) carries information about sound from the inner ear to the brain, allowing us to hear. It's also involved in balance and coordination.

The glossopharyngeal nerve (cranial nerve IX) controls swallowing, taste sensation on the back of the tongue, and the sensation of pressure in the ear.

The vagus nerve (cranial nerve X) is a long nerve that controls many involuntary functions like heart rate, breathing, digestion, and even voice production.

The spinal accessory nerve (cranial nerve XI) controls neck and shoulder movements, allowing you to turn your head and shrug.

The hypoglossal nerve (cranial nerve XII) controls tongue movements, allowing you to speak, swallow, and taste properly.

The corticospinal tract is a major pathway that delivers signals from the brain to the spinal cord, enabling voluntary muscle movements.
