Which nerves transmit the electrical impulses from the central nervous system to the muscles and glands?

Options

A. Sensory neurons
B. Motor neurons
C. Mixed neurons
D. Peripheral neurons

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question:**
- The question asks which type of nerves are responsible for transmitting electrical impulses from the central nervous system (CNS) to muscles and glands.

2. **Analyzing the Options:**
- The options provided are:
- a) Sensory neurons
- b) Motor neurons
- c) Mixed neurons
- d) Peripheral neurons

3. **Evaluating Each Option:**
- **Option a: Sensory Neurons**
- Sensory neurons are responsible for transmitting impulses from sensory organs (like skin, eyes, ears) to the central nervous system. Therefore, they do not transmit impulses from the CNS to muscles and glands.
- **Conclusion:** This option is incorrect.

- **Option b: Motor Neurons**
- Motor neurons carry electrical impulses away from the central nervous system to muscles and glands. They are specifically designed to control muscle contractions and glandular secretions.
- **Conclusion:** This option is correct.

- **Option c: Mixed Neurons**
- Mixed neurons contain both sensory and motor fibers. While they can transmit signals in both directions, they do not specifically transmit impulses solely from the CNS to muscles and glands.
- **Conclusion:** This option is incorrect.

- **Option d: Peripheral Neurons**
- Peripheral neurons refer to the nerves outside the CNS that connect the CNS to limbs and organs. They do not specifically transmit impulses from the CNS to muscles and glands.
- **Conclusion:** This option is incorrect.

4. **Final Conclusion:**
- After evaluating all the options, the correct answer is **motor neurons**, as they are the nerves that transmit electrical impulses from the central nervous system to the muscles and glands.
