Plasmalemma and cytoplasm of axon are called respectively  

Options

A. neurilemma, neuroplasm
B. sarcoplasm, sarcoplasm
C. axolemma, axoplasm
D. all the above

Answer

To answer the question regarding what the plasmalemma and cytoplasm of an axon are called respectively, we can break down the terms and their meanings step by step.

### Step-by-Step Solution:

1. **Understanding Plasmalemma**:
- The term "plasmalemma" refers to the cell membrane of a neuron. It is a biological term that describes the membrane that encloses the cell and separates its interior from the external environment.

2. **Understanding Cytoplasm**:
- The cytoplasm of a neuron is the thick solution that fills the cell. It is enclosed by the plasmalemma and contains various organelles and structures necessary for cellular function.

3. **Identifying the Specific Terms for Axon**:
- In the context of an axon, the plasmalemma is specifically referred to as **axolima**. This term describes the plasma membrane of the axon.
- The cytoplasm of the axon is referred to as **axoplasm**. This term describes the cytosol within the axon, which is crucial for propagating nerve impulses.

4. **Conclusion**:
- Therefore, the plasmalemma and cytoplasm of an axon are called **axolima** and **axoplasm** respectively.

### Final Answer:
Plasmalemma and cytoplasm of axon are called respectively **axolima** and **axoplasm**.
