Which of the following anterior pituitary hormones is linked directly to body whereas other hormones mostly control other glands ?

Options

A. Somatotropin
B. Somatocrinin
C. Somatostatin
D. Pitocin

Answer

To solve the question regarding which anterior pituitary hormone is directly linked to the body while others primarily control other glands, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Anterior Pituitary Hormones**: The anterior pituitary releases several hormones, including somatotrophin, somatocranine, somatostatin, and pitocin.

2. **Understand the Functions of Each Hormone**:
- **Somatotrophin (Growth Hormone)**: This hormone is responsible for stimulating growth and cell reproduction. It directly affects various tissues in the body, promoting growth and metabolism.
- **Somatocranine**: This is a peptide that acts as a potent growth hormone, but it primarily enhances the effects of other growth hormones rather than acting directly on body functions.
- **Somatostatin**: This hormone inhibits growth hormone release and other hormones, acting more as a regulatory hormone rather than directly stimulating body functions.
- **Pitocin (Oxytocin)**: While this hormone is involved in childbirth and lactation, it is not primarily linked to general growth or metabolic functions in the body.

3. **Determine the Hormone Linked Directly to Body Functions**: Among the hormones listed, somatotrophin (growth hormone) is the one that directly influences growth and metabolic processes in the body. The other hormones primarily regulate other glands or processes.

4. **Conclusion**: Based on the functions of these hormones, the answer to the question is **Somatotrophin**.

### Final Answer:
The anterior pituitary hormone that is linked directly to the body is **Somatotrophin** (option A).
