Endorphin is produced by

Options

A. Pituitary
B. Hypothalamus
C. Medulla oblongata
D. Both A and B

Answer

**Step-by-Step Solution:**

1. **Understanding Endorphins**: Endorphins are chemicals produced in the body that function as neurotransmitters. They are involved in pain relief and the feeling of pleasure.

2. **Identifying the Source**: The question asks where endorphins are produced. The options provided are the pituitary gland, hypothalamus, medulla oblongata, or both A and B.

3. **Role of the Hypothalamus**: The hypothalamus plays a crucial role in regulating various bodily functions and is involved in the production of endorphins. It activates the pituitary gland.

4. **Role of the Pituitary Gland**: The pituitary gland, often referred to as the "master gland," releases various hormones, including ACTH (adrenocorticotropic hormone), which is important for the production of endorphins.

5. **Production Mechanism**: When the hypothalamus activates the pituitary gland, the pituitary releases ACTH. This hormone then stimulates the release of endorphins from neurons.

6. **Conclusion**: Since both the hypothalamus and the pituitary gland are involved in the production of endorphins, the correct answer is "both A and B."

**Final Answer**: Endorphins are produced by both the pituitary gland and the hypothalamus.
