The types of cells that form glandular epithelium that secrete enzymes and buffers in the pancreas and salivary glands are :

Options

A. simple squamous epithelium
B. simple cuboidal epithelium
C. stratified cuboidal epithelium
D. transitional epithelium

Answer

To answer the question regarding the types of cells that form glandular epithelium, which secretes enzymes and buffers in the pancreas and salivary glands, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Glandular Epithelium**: Glandular epithelium is a specialized type of epithelial tissue responsible for the secretion of various substances such as enzymes, hormones, and other secretory products.

2. **Identify the Types of Epithelial Cells**: The question provides four options:
- Simple Squamous Epithelium
- Simple Cuboidal Epithelium
- Stratified Cuboidal Epithelium
- Transitional Epithelium

3. **Analyze Each Option**:
- **Simple Squamous Epithelium**: This consists of a single layer of flat cells and is not primarily involved in secretion.
- **Simple Cuboidal Epithelium**: This consists of a single layer of cube-shaped cells and is commonly found in glandular tissues, where it plays a significant role in secretion.
- **Stratified Cuboidal Epithelium**: This consists of multiple layers of cuboidal cells, but it is less common and not primarily associated with glands.
- **Transitional Epithelium**: This type of epithelium can stretch and is typically found in the urinary bladder, not in glands.

4. **Determine the Correct Answer**: Based on the analysis, the type of epithelial cell that forms glandular epithelium in the pancreas and salivary glands is the **Simple Cuboidal Epithelium**. This type of epithelium is specifically adapted for secretion.

5. **Conclusion**: Therefore, the answer to the question is **Simple Cuboidal Epithelium**.
