How much volume of neural tissue in our body is contributed by neuroglia ?

Options

A. `lt25%`
B. `gt50%`
C. `gt75%`
D. `90%`

Answer

To determine how much volume of neural tissue in our body is contributed by neuroglia, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Cells in Neural Tissue**:
- Neural tissue in the human body consists of two main types of cells: neurons (nerve cells) and neuroglial cells (glial cells).

2. **Function of Neurons vs. Neuroglia**:
- Neurons are responsible for conducting nerve impulses.
- Neuroglial cells do not conduct impulses but serve supportive roles, such as protecting neurons, maintaining homeostasis, and forming myelin sheaths around nerve fibers.

3. **Proportion of Neuroglial Cells**:
- It is noted that neuroglial cells outnumber neurons significantly. Specifically, it is mentioned that there are about 25 times more neuroglial cells than neurons in the body.

4. **Volume Contribution**:
- Since neuroglial cells are more abundant, they contribute a significant volume to the neural tissue. It is stated that neuroglial cells make up more than half of the volume of neural tissue.

5. **Evaluate the Options**:
- The options provided include:
- Lesser than 25%
- Greater than 50%
- Greater than 75%
- 90%
- Given that neuroglial cells constitute more than half of the neural tissue volume, the correct choice is "greater than 50%".

### Final Answer:
The volume of neural tissue in our body contributed by neuroglia is **greater than 50%**.
