Collateral fibres are given out along its way in

Options

A. muscle fibre
B. axon
C. dendron
D. dendrites

Answer

To solve the question about where collateral fibers are given out along their way, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Collateral Fibers**:
- Collateral fibers are small branches that extend from a main structure at a right angle. In the context of the nervous system, these fibers are associated with nerve fibers.

2. **Identifying the Structures**:
- The question provides four options: muscle fiber, axon, dendron, and dendrites. We need to analyze each option to determine where collateral fibers are found.

3. **Analyzing Each Option**:
- **Muscle Fiber**: Muscle fibers are responsible for contraction and do not have collateral fibers extending from them.
- **Axon**: An axon is a part of a neuron that transmits impulses away from the cell body. Collateral fibers can extend from the axon at right angles, making this a strong candidate.
- **Dendron**: A dendron is a part of a neuron that receives signals. It does not typically give rise to collateral fibers.
- **Dendrites**: Dendrites are extensions of a neuron that receive signals from other neurons. They do not produce collateral fibers.

4. **Conclusion**:
- Based on the analysis, the correct answer is that collateral fibers are given out along the way in the **axon**.

### Final Answer:
- The correct option is **B. Axon**.
