Hypothalamus secrete

Options

A. Peptide hormone only
B. Amine hormones only
C. Inhibiting and releasing hormones
D. Gonadotropins

Answer

**Step-by-Step Solution:**

1. **Understanding the Hypothalamus**: The hypothalamus is a small region of the brain that plays a crucial role in hormone production and regulation of various bodily functions. It connects the nervous system to the endocrine system via the pituitary gland.

2. **Identifying Hormones Secreted by the Hypothalamus**: The hypothalamus secretes several types of hormones, including:
- Releasing hormones (which stimulate the pituitary gland to release hormones)
- Inhibiting hormones (which inhibit the release of hormones from the pituitary)
- Various other hormones such as growth hormone-releasing hormone (GHRH), corticotropin-releasing hormone (CRH), and somatostatin.

3. **Analyzing the Options**:
- **Option 1: Peptide hormones only** - This is incorrect as the hypothalamus secretes a variety of hormones, not limited to peptides.
- **Option 2: Amine hormones only** - This is also incorrect since the hypothalamus secretes more than just amine hormones.
- **Option 3: Inhibiting and releasing hormones** - While this is true, it does not encompass all the hormones produced by the hypothalamus.
- **Option 4: Gonadotropines** - The hypothalamus does secrete gonadotropin-releasing hormone (GnRH), which stimulates the release of gonadotropins from the pituitary gland.

4. **Conclusion**: Based on the analysis, the best answer to the question "Hypothalamus secretes" is **Option 4: Gonadotropines**.
