Question

Match the selected cranial nerves with their function.

1. Controls muscles of mastication
2. Innervates tongue muscles
3. Controls visceral and cardiac muscle
4. Control of facial muscles
5. Vision
6. Equilibrium and hearing
7. Innervates pharynx

Answer 1

Cranial nerve VII is responsible for facial expressions, cranial nerve VIII is dedicated to equilibrium and hearing, and cranial nerve IX innervates the pharynx. Each cranial nerve has specific functions such as controlling senses, motor skills, or both in the head and neck.

Step-by-step explanation:

The selected cranial nerves and their corresponding functions can be matched as follows:

• The facial nerve (cranial nerve VII) controls the muscles of facial expression, making it responsible for smiling, frowning, and other expressions.
• The vestibulocochlear nerve (cranial nerve VIII) is dedicated to equilibrium and hearing.
• The glossopharyngeal nerve (cranial nerve IX) primarily innervates the pharynx (throat), playing a role in swallowing and taste sensation.

There are 12 cranial nerves in total, each with a specific set of functions that control the senses, motor skills, or a combination of both in the head and neck region.
