If sensory fibres of a nerve carry the impulses from fungiform and filiform taste papillae of tongue to pons, the nerve is

Options

A. Trigeminal
B. Facial
C. Glossopharyngeal
D. Vagus

Answer

To solve the question regarding which nerve carries sensory impulses from the fungiform and filiform taste papillae of the tongue to the pons, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Function of the Nerves**:
- We need to understand the basic functions of the cranial nerves involved in taste sensation. The relevant cranial nerves are the trigeminal nerve (V), facial nerve (VII), glossopharyngeal nerve (IX), and vagus nerve (X).

2. **Examine the Trigeminal Nerve (V)**:
- The trigeminal nerve primarily carries sensory information from the face, including touch and pain, but it is not primarily responsible for taste sensation. Therefore, it is not the correct answer.

3. **Examine the Facial Nerve (VII)**:
- The facial nerve is responsible for taste sensations from the anterior two-thirds of the tongue, which includes the fungiform papillae. This nerve carries sensory fibers that transmit taste information to the pons.

4. **Examine the Glossopharyngeal Nerve (IX)**:
- The glossopharyngeal nerve carries taste sensations from the posterior one-third of the tongue. While it is involved in taste, it does not carry impulses from the fungiform and filiform papillae.

5. **Examine the Vagus Nerve (X)**:
- The vagus nerve is primarily involved in autonomic functions and does not play a significant role in taste sensation from the tongue.

6. **Conclusion**:
- Based on the functions of the nerves, the facial nerve (VII) is the correct answer as it carries sensory impulses from the fungiform and filiform taste papillae of the tongue to the pons.

### Final Answer:
The nerve that carries the impulses from the fungiform and filiform taste papillae of the tongue to the pons is the **Facial Nerve (VII)**.
