The adrenocorticotrophic hormone secreted by anterior pituitary stimulates the secretion of :

Options

A. Glucocorticoids from adrenal glands
B. Adrenaline from adrenal gland
C. Epinephrine from adrenal gland
D. Adrenaline from nephrons

Answer

To solve the question regarding the adrenocorticotropic hormone (ACTH) secreted by the anterior pituitary and its role in stimulating the secretion of other hormones, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding ACTH**:
- The adrenocorticotropic hormone (ACTH) is produced by the anterior pituitary gland. It plays a crucial role in the endocrine system.

**Hint**: Remember that ACTH is a hormone that originates from the anterior pituitary.

2. **Target of ACTH**:
- ACTH primarily targets the adrenal glands, which are located on top of each kidney.

**Hint**: Think about where ACTH acts in the body; it’s important to know the location of the adrenal glands.

3. **Adrenal Gland Structure**:
- The adrenal gland consists of two main parts: the outer cortex and the inner medulla. The cortex is further divided into three zones: zona glomerulosa, zona fasciculata, and zona reticularis.

**Hint**: Familiarize yourself with the structure of the adrenal gland and its divisions.

4. **Hormones Secreted by the Adrenal Cortex**:
- The zona glomerulosa secretes mineralocorticoids (e.g., aldosterone), the zona fasciculata secretes glucocorticoids (e.g., cortisol), and the zona reticularis secretes androgens.

**Hint**: Focus on the specific hormones produced in each zone of the adrenal cortex.

5. **Role of ACTH**:
- ACTH specifically stimulates the secretion of glucocorticoids from the zona fasciculata of the adrenal cortex. The primary glucocorticoid is cortisol.

**Hint**: Remember that ACTH is linked to the stress response and primarily influences cortisol production.

6. **Conclusion**:
- Therefore, the correct answer to the question is that ACTH stimulates the secretion of glucocorticoids from the adrenal gland.

**Hint**: Summarize your findings to confirm the relationship between ACTH and glucocorticoids.

### Final Answer:
The adrenocorticotrophic hormone (ACTH) secreted by the anterior pituitary stimulates the secretion of glucocorticoids from the adrenal gland.
