Options

A. Endothelium
B. Endocardium
C. Ependymal cells
D. Mesothelium

Answer

To solve the question about the epithelial tissue that lines the spinal cord, we will analyze each option provided and determine which one is correct.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the specific type of epithelial tissue that lines the spinal cord.

2. **Analyzing the Options**:
- **Option 1: Endothelium**: This type of tissue consists of a single layer of squamous cells that line the interior of blood vessels. Since it is related to blood vessels and not the spinal cord, this option is incorrect.

- **Option 2: Endocardium**: The endocardium is the innermost layer of the heart. It is not related to the spinal cord, so this option is also incorrect.

- **Option 3: Ependymal Cells**: Ependymal cells are a type of epithelial tissue that line the spinal cord and the ventricles of the brain. They play a role in the production and circulation of cerebrospinal fluid and provide protection to the spinal cord. This option is likely to be correct.

- **Option 4: Mesothelium**: Mesothelium is a type of epithelial tissue that lines the body cavities and covers the organs within those cavities. It is not related to the spinal cord, making this option incorrect.

3. **Conclusion**: After analyzing all options, the correct answer is **Option 3: Ependymal Cells**, as they specifically line the spinal cord.

### Final Answer:
The epithelial tissue which lines the spinal cord is known as **Ependymal Cells**.
