The primary target of the hormones of hypothalamus is

Options

A. Pineal gland
B. Thymus
C. Pituitary
D. Testis

Answer

**Step-by-Step Solution:**

1. **Understanding the Hypothalamus:**
- The hypothalamus is a small region located at the base of the brain. It plays a crucial role in linking the nervous system to the endocrine system.

2. **Function of the Hypothalamus:**
- One of the primary functions of the hypothalamus is to produce hormones that regulate the pituitary gland. It acts as a control center for various bodily functions, including temperature regulation, hunger, thirst, and circadian rhythms.

3. **Identifying the Target of Hypothalamic Hormones:**
- The hormones secreted by the hypothalamus primarily target the pituitary gland. The hypothalamus releases hormones that either stimulate or inhibit the release of hormones from the pituitary gland.

4. **Examining the Options:**
- **Pineal Gland:** Produces melatonin, which regulates sleep-wake cycles but is not the primary target of hypothalamic hormones.
- **Thymus:** Involved in immune function and T lymphocyte production but is not directly targeted by hypothalamic hormones.
- **Pituitary Gland:** The primary target of hypothalamic hormones, controlling various endocrine functions.
- **Testes:** Male reproductive organs responsible for gamete production, not the target of hypothalamic hormones.

5. **Conclusion:**
- The primary target of the hormones of the hypothalamus is the **pituitary gland**.

**Final Answer:**
The primary target of the hormones of the hypothalamus is the **pituitary gland**.
