Cell body of neuron is called

Options

A. Nissl body
B. Neurolemma
C. Oligodendrocyte
D. Perikaryon.

Answer

**Step-by-Step Solution:**

1. **Understanding Neurons**: Neurons are specialized cells responsible for transmitting nerve signals throughout the body. They consist of different parts, including the cell body, dendrites, and axon.

2. **Identifying the Cell Body**: The cell body of a neuron is the central part that contains the nucleus and other organelles necessary for the cell's functioning.

3. **Terminology**: The cell body of a neuron is specifically referred to as the "perikaryon" or "neurocyton". This term emphasizes its role as the main part of the neuron where metabolic activities occur.

4. **Distinguishing Other Options**:
- **Nissl Body**: This is not the cell body but refers to the rough endoplasmic reticulum in neurons that is involved in protein synthesis.
- **Neurolemma**: This is the outermost layer of the nerve fiber, which surrounds the axon and is not the cell body.
- **Oligodendrocyte**: These are glial cells that produce the myelin sheath around axons in the central nervous system, not part of the neuron’s cell body.

5. **Conclusion**: Based on the definitions and functions of the parts of a neuron, the correct answer to the question "Cell body of neuron is called" is **perikaryon**.
