One of the following is related only to myelinated neurons. Identify it

Options

A. Dendrites
B. Axon
C. Telodendrites
D. Nodes of ranvier

Answer

To solve the question of identifying which option is related only to myelinated neurons, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Myelinated Neurons**: Myelinated neurons are a type of neuron characterized by the presence of a myelin sheath around their axons. This sheath is formed by Schwann cells in the peripheral nervous system.

2. **Identify Key Features**: The myelin sheath serves to insulate the axon, allowing for faster transmission of electrical impulses along the neuron. This is crucial for efficient communication in the nervous system.

3. **Analyze the Options**: The question provides several options. We need to evaluate each option to determine which one is specifically related to myelinated neurons.

4. **Focus on the Axon**: Since the myelin sheath surrounds the axon, it is the axon that is directly related to myelinated neurons. Other components of the neuron, such as dendrites or the cell body (cytone), do not have myelin sheaths.

5. **Select the Correct Option**: Based on the analysis, the only option that is related exclusively to myelinated neurons is the axon.

6. **Conclusion**: Therefore, the answer to the question is option **b: axon**.
