Which of the following endocrine gland's hormones binds to their specific receptors present inside the target cells to form hormone - receptor complex ?

Options

A. Pituitary hormones
B. Adrenal medulla hormones
C. Hypothamic hormones
D. Adrenal cortex hormones

Answer

To solve the question, we need to identify which of the listed endocrine glands produces hormones that bind to specific receptors located inside the target cells to form a hormone-receptor complex.

### Step-by-Step Solution:

1. **Understanding Hormone Receptors**:
- Hormones can bind to receptors that are either on the cell membrane or inside the cell.
- The binding location is crucial for understanding how hormones exert their effects.

2. **Identifying the Types of Hormones**:
- **Pituitary Hormones**: These are primarily peptide hormones that bind to receptors on the cell membrane.
- **Adrenal Medulla Hormones**: These include catecholamines (like epinephrine), which also bind to membrane receptors.
- **Hypothalamic Hormones**: Similar to pituitary hormones, these are also peptide hormones and bind to membrane receptors.
- **Adrenal Cortex Hormones**: These include steroid hormones (like cortisol, aldosterone) which are lipophilic and can pass through the cell membrane to bind to receptors inside the target cells.

3. **Determining the Correct Option**:
- Since we are looking for hormones that bind to receptors inside the target cells, we focus on the Adrenal Cortex Hormones, as they are steroid hormones and their receptors are located inside the cells.

4. **Conclusion**:
- The correct answer is **Adrenal Cortex Hormones** because they bind to specific receptors inside the target cells to form a hormone-receptor complex.

### Final Answer:
The hormones from the **Adrenal Cortex** bind to their specific receptors present inside the target cells to form a hormone-receptor complex.
