The function of an axon is :

Options

A. Transformation of nerve impulse
B. Reception of stimuli from neurons
C. Reception of external stimuli
D. Transmission of nerve impulse

Answer

### Step-by-Step Solution:

1. **Understanding the Structure of an Axon**:
- An axon is a long, thin fiber that extends from a neuron (nerve cell). It is a crucial part of the nervous system.

2. **Identifying the Primary Function**:
- The main function of an axon is to transmit electrical signals, known as nerve impulses, away from the neuron's cell body to other neurons, muscles, or glands.

3. **Evaluating the Options**:
- Let's examine the provided options to determine which one correctly describes the function of an axon:
- **Option A**: Transformation of the nerve impulse - This is incorrect as axons do not transform impulses; they transmit them.
- **Option B**: Reception of stimuli from neurons - This is also incorrect because axons do not receive stimuli; they transmit signals.
- **Option C**: Reception of external stimuli - This is incorrect as well; axons do not receive external stimuli directly.
- **Option D**: Transmission of the nerve impulses - This is the correct option, as it accurately describes the primary function of an axon.

4. **Conclusion**:
- The function of an axon is primarily the transmission of nerve impulses, which facilitates communication within the nervous system.

### Final Answer:
The function of an axon is the transmission of nerve impulses.
