In the central nervous system, interneuron space is filled by

Options

A. connective tissue
B. nerve cells
C. neuroglia cells
D. axons

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks what fills the inter-neuron space in the central nervous system (CNS). This refers to the spaces between the neurons.

2. **Identifying Key Components**: In the CNS, the primary cells are neurons (nerve cells), which consist of a cell body, axon, and axon terminals. The inter-neuron space is the area between these neurons.

3. **Recognizing the Role of Glial Cells**: The inter-neuron space is not just empty; it is filled with supportive cells known as glial cells. These cells play crucial roles in supporting and protecting neurons.

4. **Types of Glial Cells**: The main types of glial cells present in the CNS include:
- Microglia: These are the immune cells of the CNS, responsible for removing debris and dead cells.
- Oligodendrocytes: These cells produce the myelin sheath that insulates axons, facilitating faster signal transmission.
- Astrocytes: Also known as astroglia or star-shaped cells, they provide structural support and help maintain the blood-brain barrier.

5. **Conclusion**: Based on the information, the inter-neuron space in the central nervous system is filled with neuroglia cells, which include microglia, oligodendrocytes, and astrocytes.

**Final Answer**: In the central nervous system, the inter-neuron space is filled by neuroglia cells.
