Hypoglossal nerve controls the movements of

Options

A. ear
B. heart
C. tongue
D. limbs

Explanation

### Step-by-Step Solution:

1. **Identify the Nerve**: The question asks about the hypoglossal nerve. It is important to recognize that this is one of the 12 pairs of cranial nerves in the human body.

2. **Understand the Function of the Hypoglossal Nerve**: The hypoglossal nerve is primarily a motor nerve. Its main function is to control muscle movements.

3. **Determine What the Hypoglossal Nerve Controls**: The hypoglossal nerve specifically controls the movements of the tongue. The term "hypoglossal" itself provides a clue, as "glossal" refers to the tongue.

4. **Differentiate from Other Cranial Nerves**: While the hypoglossal nerve controls the tongue, it's helpful to know that other cranial nerves control different functions:
- The vestibulocochlear nerve (8th cranial nerve) is responsible for hearing.
- The vagus nerve (10th cranial nerve) regulates heart functions.
- Limb movements are controlled by a combination of nerves, primarily from the brachial and lumbar plexuses.

5. **Conclude the Answer**: Based on the information gathered, the hypoglossal nerve controls the movements of the tongue.

### Final Answer:
The hypoglossal nerve controls the movements of the tongue.
