The anterior pitiuitary hormone that does not stimulate another endocrine gland is

Options

A. Somatotrophin
B. Thyrotrophin
C. Gonadotrophin
D. Adrenocorticotrophin

Answer

To answer the question regarding which anterior pituitary hormone does not stimulate another endocrine gland, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Anterior Pituitary Hormones**: The anterior pituitary secretes several hormones, including:
- Growth Hormone (GH)
- Thyroid Stimulating Hormone (TSH)
- Adrenocorticotropic Hormone (ACTH)
- Gonadotropins (LH and FSH)

2. **Understand the Function of Each Hormone**:
- **Growth Hormone (GH)**: Primarily stimulates growth in bones and muscles. It does not stimulate another endocrine gland.
- **Thyroid Stimulating Hormone (TSH)**: Stimulates the thyroid gland to produce thyroid hormones (like thyroxine).
- **Adrenocorticotropic Hormone (ACTH)**: Stimulates the adrenal cortex to produce corticosteroids.
- **Gonadotropins (LH and FSH)**: Stimulate the gonads (ovaries and testes) to produce sex hormones and gametes.

3. **Determine Which Hormone Does Not Stimulate Another Endocrine Gland**:
- From the above functions, it is clear that GH (Somatotropin) does not act on another endocrine gland but directly affects tissues like bones and muscles.

4. **Conclusion**: The anterior pituitary hormone that does not stimulate another endocrine gland is **Growth Hormone (GH)**, also known as **Somatotropin**.

### Final Answer:
The anterior pituitary hormone that does not stimulate another endocrine gland is **Growth Hormone (GH)** or **Somatotropin**.
