In thyroid follicle which type of epithelial tissue is present

Options

A. Sqamous
B. Cuboidal
C. Transitional
D. Columnar

Answer

**Step-by-Step Solution:**

1. **Understanding the Structure of Thyroid Follicles:**
- Thyroid follicles are spherical structures within the thyroid gland that are responsible for the production and secretion of thyroid hormones.

2. **Identifying the Type of Epithelial Tissue:**
- The epithelial tissue present in the thyroid follicles is primarily cuboidal epithelium. This type of epithelium consists of cube-shaped cells that form a single layer around the follicle.

3. **Function of Cuboidal Epithelium in Thyroid Follicles:**
- The cuboidal epithelial cells in the thyroid follicles are involved in the synthesis and secretion of thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones play a crucial role in regulating metabolism and growth.

4. **Comparison with Other Types of Epithelial Tissue:**
- Other types of epithelial tissues mentioned include:
- **Squamous Epithelium:** Found in areas requiring protection, such as the skin and alveoli.
- **Columnar Epithelium:** Found in the digestive tract, involved in secretion and absorption.
- **Transitional Epithelium:** Found in the urinary bladder, providing elasticity.

5. **Conclusion:**
- Based on the structure and function of the thyroid follicles, the correct type of epithelial tissue present is cuboidal epithelium.

**Final Answer:**
The type of epithelial tissue present in thyroid follicles is cuboidal epithelium.
