Which of the following cranial nerve controls the movement of tongue ?

Options

A. V cranial nerve
B. X cranial nerve
C. XII cranial nerve
D. VIII cranial nerve

Answer

To determine which cranial nerve controls the movement of the tongue, we will analyze the options provided:

1. **Understanding Cranial Nerves**: Cranial nerves are nerves that arise directly from the brain. There are 12 pairs of cranial nerves, each with specific functions.

2. **Evaluating the Options**:
- **Option 1: Fifth Cranial Nerve (Trigeminal Nerve)**: This nerve is primarily responsible for sensation in the face and motor functions such as biting and chewing. It does not control tongue movement.
- **Option 2: Tenth Cranial Nerve (Vagus Nerve)**: The vagus nerve controls functions of the heart, lungs, and digestive tract, but it does not control the movement of the tongue.
- **Option 3: Twelfth Cranial Nerve (Hypoglossal Nerve)**: The hypoglossal nerve is specifically responsible for controlling the muscles of the tongue, making it essential for tongue movement.
- **Option 4: Eighth Cranial Nerve (Vestibulocochlear Nerve)**: This nerve is involved in hearing and balance, not in the movement of the tongue.

3. **Conclusion**: Based on the analysis, the cranial nerve that controls the movement of the tongue is the **Twelfth Cranial Nerve (Hypoglossal Nerve)**.

### Final Answer:
The cranial nerve that controls the movement of the tongue is the **Hypoglossal Nerve (Twelfth Cranial Nerve)**.
