Name the cells in the mucosal epithelium that helps in lubrication

Answer

### Step-by-Step Solution:

1. **Identify the Mucosal Epithelium**: The mucosal epithelium is a type of tissue that lines various cavities and surfaces in the body, including the gastrointestinal tract.

2. **Understand the Function of Mucosal Epithelium**: One of the primary functions of the mucosal epithelium is to provide lubrication, which is essential for the smooth passage of food and other substances.

3. **Identify the Cells Responsible for Lubrication**: The specific cells within the mucosal epithelium that are responsible for lubrication are known as goblet cells.

4. **Describe Goblet Cells**: Goblet cells are specialized epithelial cells that are unicellular, meaning they consist of a single cell.

5. **Function of Goblet Cells**: Goblet cells secrete mucus, which serves as a lubricating agent. This mucus helps to reduce friction and facilitates the movement of materials through the digestive tract.

6. **Conclusion**: Therefore, the cells in the mucosal epithelium that help in lubrication are called goblet cells.
