Endorphin lowers perception of pain through

Options

A. Reduction in nerve impulse transmission
B. Sedating pain receptors
C. Sedating pain perceptors
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Endorphins**: Endorphins are neurotransmitters produced by the body that help to relieve pain and induce feelings of pleasure or euphoria. They are often released in response to stress or pain.

2. **Mechanism of Action**: Endorphins lower the perception of pain primarily by binding to opioid receptors in the nervous system. These receptors are part of the body's pain control system.

3. **Reduction of Nerve Impulse Transmission**: When endorphins bind to these opioid receptors, they inhibit the transmission of pain signals from the site of injury to the brain. This means that the nerve impulses that would normally carry pain signals are reduced.

4. **Other Options**: The other options mentioned, such as "sedating pain receptors" and "sedating pain perceptors," are not accurate descriptions of how endorphins function. Endorphins do not sedate the receptors themselves; rather, they modulate the transmission of pain signals.

5. **Conclusion**: Therefore, the primary way endorphins lower the perception of pain is through the reduction in nerve impulse transmission.

**Final Answer**: The correct option is "reduction in nerve impulse transmission."
