Sheath of schwann occurs on

Options

A. Neurons
B. Axons
C. Dendrons
D. Neuroglia

Answer

**Step-by-Step Solution:**

1. **Understanding Schwann Cells**: Schwann cells, also known as neurolemmocytes, are a type of glial cell found in the Peripheral Nervous System (PNS). They play a crucial role in the formation of myelin sheath around the axons of neurons.

2. **Function of Schwann Cells**: The primary function of Schwann cells is to wrap around the axons of motor and sensory neurons. This wrapping forms the myelin sheath, which is essential for the proper conduction of nerve impulses.

3. **Identifying the Structure**: The question asks where the sheath of Schwann occurs. Since Schwann cells are responsible for myelination, we need to identify the structure they cover.

4. **Myelination Process**: The process of wrapping the axon with Schwann cells is known as myelination. This process enhances the speed of electrical impulses along the axon.

5. **Conclusion**: Based on the above understanding, the sheath of Schwann occurs on the axon of motor and sensory neurons. Therefore, the correct answer is that the sheath of Schwann occurs on the axon.

**Final Answer**: The sheath of Schwann occurs on the axon.
