Secretory part of sweet gland is composed of :-

Options

A. Cubodial epithelium
B. Columner Epithelium
C. Pseudostratified epithelium
D. Squamous epithelium

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks about the composition of the secretory part of the sweat gland.

2. **Understand Sweat Glands**: Sweat glands are exocrine glands located in the skin that secrete sweat. They are classified as merocrine glands, which means they release their secretions through exocytosis using secretory vesicles.

3. **Analyze the Options**: The options provided are:
- A) Cuboidal epithelium
- B) Columnar epithelium
- C) Pseudostratified epithelium
- D) Squamous epithelium

4. **Determine the Correct Type of Epithelium**:
- **Cuboidal Epithelium**: This type of epithelium consists of cube-shaped cells that are tightly packed together. This is the correct type of epithelium found in the secretory part of the sweat gland.
- **Columnar Epithelium**: These cells are taller and column-shaped, which does not match the structure of sweat glands.
- **Pseudostratified Epithelium**: This type appears to be stratified but is not truly so; it is not found in sweat glands.
- **Squamous Epithelium**: These are flat cells, which also do not make up the secretory part of sweat glands.

5. **Conclusion**: The secretory part of the sweat gland is composed of **simple cuboidal epithelium**. Therefore, the correct answer is option A.

**Final Answer**: A) Cuboidal epithelium
