Plasmalemma of axon is called

Options

A. Axolemma
B. Neurilemma
C. Sacrolemma
D. None of these.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the specific term used to refer to the plasmalemma (cell membrane) of an axon.

2. **Identifying the Options**: The options provided include:
- A) Axolemma
- B) Neurilemma
- C) Sarcolemma
- D) None of these

3. **Analyzing Each Option**:
- **Option A: Axolemma** - This term specifically refers to the plasma membrane of an axon. It is the correct term for the cell membrane surrounding the axon.
- **Option B: Neurilemma** - This term refers to the outermost layer of the nerve fiber, which includes the Schwann cell membrane. It is not specific to the axon itself.
- **Option C: Sarcolemma** - This term refers to the plasma membrane of muscle fibers, not axons.
- **Option D: None of these** - This option would imply that none of the provided terms are correct, which is not the case.

4. **Conclusion**: Based on the analysis, the correct answer is **Option A: Axolemma**.

**Final Answer**: The plasmalemma of an axon is called **Axolemma**.
