Which one of these transmits nerve impulse away from CNS ?

Options

A. Optic
B. Olfactory
C. Abducens
D. Auditory

Answer

To determine which nerve transmits nerve impulses away from the Central Nervous System (CNS), we need to analyze the functions of the given options:

1. **Understanding the Options**:
- **Optic Nerve**: This nerve is responsible for transmitting visual information from the retina to the brain. It is a sensory nerve.
- **Olfactory Nerve**: This nerve transmits sensory information related to smell from the nasal cavity to the brain.
- **Abducens Nerve**: This is a motor nerve that controls the lateral rectus muscle, which is responsible for moving the eye outward. It transmits impulses from the brain to the muscle, indicating a movement away from the CNS.
- **Auditory Nerve**: Also known as the vestibulocochlear nerve, it transmits sensory information related to hearing and balance from the inner ear to the brain.

2. **Identifying the Correct Answer**:
- The question specifically asks for the nerve that transmits impulses **away** from the CNS.
- Among the options, the **Abducens Nerve** is the only one that transmits motor impulses from the CNS to the muscles, thus controlling movement.

3. **Conclusion**:
- Therefore, the correct answer is the **Abducens Nerve** (Option 3).
