ADH is produced in

Options

A. Pars distalis
B. Pars nervosa
C. Pars intermedia
D. Hypothalamus

Answer

**Step-by-Step Solution:**

1. **Understanding ADH**: ADH stands for Anti-Diuretic Hormone, which is crucial for regulating water balance in the body. It helps control the amount of water reabsorbed by the kidneys.

2. **Identifying the Options**: The question provides three options regarding where ADH is produced:
- Option 1: Pars distalis
- Option 2: Pars nervosa
- Option 3: Pars intermedia

3. **Analyzing Pars Distalis**:
- Pars distalis is part of the anterior pituitary gland.
- It produces hormones such as growth hormone, prolactin, and thyroid-stimulating hormone, but it does not produce ADH.

4. **Analyzing Pars Nervosa**:
- Pars nervosa is part of the posterior pituitary gland (also known as neurohypophysis).
- While it stores and releases ADH and oxytocin, it does not produce ADH. Therefore, this option is incorrect.

5. **Analyzing Pars Intermedia**:
- Pars intermedia is another part of the pituitary gland.
- It primarily produces melanocyte-stimulating hormone (MSH) and does not produce ADH. Thus, this option is also incorrect.

6. **Conclusion**:
- The correct answer is that ADH is produced in the hypothalamus.
- While it is stored and released by the posterior pituitary (pars nervosa), the synthesis occurs in the hypothalamus.

**Final Answer**: ADH is produced in the hypothalamus.
