Lining of brain ventricle & central canal of spinal cord is called as :-

Options

A. Ependyma
B. Endothelium
C. Mesothelium
D. Neurosensory

Answer

**Step-by-Step Solution:**

1. **Identify the Structures**: The question asks about the lining of the brain ventricle and the central canal of the spinal cord.
- The brain ventricles are hollow spaces filled with cerebrospinal fluid (CSF).
- The central canal is the central lumen of the spinal cord, also containing CSF.

2. **Determine the Type of Lining**: We need to find out what type of tissue lines these structures.
- The lining of the brain ventricles and the central canal is specialized for the functions associated with CSF.

3. **Recall the Options**: The options given are:
- Endothelium
- Mesothelium
- Neurosensory
- Ependyma

4. **Analyze Each Option**:
- **Endothelium**: This is the lining of blood vessels, not relevant here.
- **Mesothelium**: This lines the body cavities and organs, not applicable to the brain ventricles or spinal canal.
- **Neurosensory**: These are cells associated with the nervous system but do not line the ventricles or central canal.
- **Ependyma**: This is the correct lining that surrounds the brain ventricles and central canal.

5. **Conclusion**: The lining of the brain ventricle and the central canal of the spinal cord is called **Ependyma**.

**Final Answer**: Ependyma
