Oxytocin and ADH are produced by hypothalamus and released from

Options

A. Anterior pituitary
B. Posterior pituitary
C. Pineal gland
D. Thymus

Answer

To solve the question regarding where oxytocin and ADH (antidiuretic hormone) are released from, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Source of Hormones**:
- Oxytocin and ADH are hormones produced by the hypothalamus.

2. **Understand the Pathway**:
- After their production in the hypothalamus, these hormones do not act directly. Instead, they are transported down the axons of the hypothalamic neurons.

3. **Locate the Release Site**:
- The hormones are stored and released from the posterior pituitary gland, also known as the neurohypophysis.

4. **Evaluate the Options**:
- The options provided are:
- a) Anterior pituitary
- b) Posterior pituitary
- c) Pineal gland
- d) Thymus
- Since we established that oxytocin and ADH are released from the posterior pituitary, we can eliminate the other options:
- Anterior pituitary is responsible for different hormones (e.g., FSH, LH).
- Pineal gland secretes melatonin.
- Thymus is involved in immune function and secretes thymosin.

5. **Conclusion**:
- The correct answer is **posterior pituitary**.

### Final Answer:
Oxytocin and ADH are produced by the hypothalamus and released from the **posterior pituitary**.
