Peptides produced by nerve cells of brain which overcome the feeling of pain are

Options

A. Encephalins
B. Endorphins
C. Growth hormone
D. Insulin

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for peptides produced by nerve cells in the brain that help alleviate the feeling of pain.

2. **Identifying Key Terms**: The key terms in the question are "peptides," "nerve cells," "brain," and "overcome the feeling of pain."

3. **Analyzing the Options**: The options given are:
- A) Encephalin
- B) Endorphins
- C) Growth hormone
- D) Insulin

4. **Researching the Functions of Each Option**:
- **Encephalin**: A type of peptide that is known to bind to opiate receptors in the brain, which can help block pain signals.
- **Endorphins**: These are also peptides that can relieve pain and induce feelings of pleasure, but they are not specifically produced by nerve cells in the brain.
- **Growth Hormone**: This hormone is involved in growth and metabolism, not pain relief.
- **Insulin**: This hormone regulates glucose levels in the blood and is not related to pain relief.

5. **Determining the Correct Answer**: Based on the functions of the peptides:
- Encephalin is specifically known for its role in pain relief by binding to opiate receptors in the brain. Therefore, it is the correct answer.

6. **Conclusion**: The peptides produced by nerve cells of the brain that overcome the feeling of pain are **Encephalin**.

**Final Answer**: Encephalin
