Trochlear , trigeminal and glossopharyngeal represent cranial nerves number

Options

A. IV,V and IX
B. VI,IX and XI
C. V,III and II
D. XI,I and XII

Answer

To determine the cranial nerve numbers represented by the Trochlear, Trigeminal, and Glossopharyngeal nerves, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Names of the Nerves**: We need to find out the cranial nerves corresponding to the names given: Trochlear, Trigeminal, and Glossopharyngeal.

2. **Know the Cranial Nerve Numbers**:
- The **Trochlear nerve** is the **4th cranial nerve** (CN IV).
- The **Trigeminal nerve** is the **5th cranial nerve** (CN V).
- The **Glossopharyngeal nerve** is the **9th cranial nerve** (CN IX).

3. **Compile the Information**: From the above information, we can summarize:
- Trochlear = CN IV
- Trigeminal = CN V
- Glossopharyngeal = CN IX

4. **Select the Correct Option**: Based on the cranial nerve numbers identified:
- The correct sequence is 4th, 5th, and 9th cranial nerves.

5. **Choose the Correct Answer**: The question asks for the option that corresponds to these numbers. The correct answer is option 1, which lists the cranial nerves as 4th, 5th, and 9th.

### Final Answer:
The cranial nerves Trochlear, Trigeminal, and Glossopharyngeal represent cranial nerve numbers **4, 5, and 9** respectively, making option 1 the correct answer.
