The central canal of spinal cord is lined by

Options

A. Goblet cells
B. Epithelial tissue
C. Ependymal cells
D. Keratinized epithelium

Answer

To answer the question "The central canal of spinal cord is lined by," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structure**: The central canal is a narrow channel located in the center of the spinal cord. It is an important structure for the circulation of cerebrospinal fluid (CSF).

2. **Understand the Lining Cells**: The cells that line the central canal are specialized types of cells. We need to determine which type of cells are responsible for this lining.

3. **Evaluate the Options**:
- **Option A: Goblet Cells** - These are specialized epithelial cells found in mucous membranes, primarily in the intestines and respiratory tract. They are not found in the spinal cord.
- **Option B: Epithelial Tissue** - While the central canal is lined by a type of epithelial tissue, this option is too broad and does not specify the exact type.
- **Option C: Ependymal Cells** - These are a specific type of epithelial-like cells that line the central canal of the spinal cord and the ventricles of the brain. They play a crucial role in the production and circulation of cerebrospinal fluid.
- **Option D: Keratinized Epithelium** - This type of epithelium is found in areas such as the skin, and it is not present in the central canal.

4. **Select the Correct Answer**: Based on the evaluation, the correct answer is **Option C: Ependymal Cells**. These cells specifically line the central canal of the spinal cord.

### Final Answer:
The central canal of the spinal cord is lined by **ependymal cells**.
