Hassall's corpuscles are found in

Options

A. Thyroid
B. Thymus
C. Adrenal
D. Pineal.

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks where Hassall's corpuscles are found among the given options: thyroid, thymus, adrenal, and pineal gland.

2. **Understand Hassall's Corpuscles**: Hassall's corpuscles are specialized structures that are primarily associated with the thymus gland. They are spherical or ovoid in shape and are composed of eosinophilic cells.

3. **Examine Each Option**:
- **Thyroid Gland**: This gland is responsible for the secretion of hormones such as T3 (triiodothyronine) and T4 (thyroxine). It does not contain Hassall's corpuscles. Therefore, this option is incorrect.
- **Thymus Gland**: This gland is crucial for the development of T lymphocytes and is known to contain Hassall's corpuscles in its medulla. This option is correct.
- **Adrenal Gland**: The adrenal gland consists of the adrenal cortex and medulla, which secrete hormones like aldosterone, cortisol, adrenaline, and noradrenaline. It does not contain Hassall's corpuscles. Thus, this option is incorrect.
- **Pineal Gland**: This gland secretes melatonin, which regulates sleep-wake cycles. It does not have Hassall's corpuscles, making this option incorrect as well.

4. **Conclusion**: Based on the analysis, the correct answer is that Hassall's corpuscles are found in the **thymus gland**.

**Final Answer**: Hassall's corpuscles are found in the **thymus gland**.
