A Normal Pain Response

When we experience pain, it's typically a sign that something is wrong in our body.

A normal pain response involves a few different steps:

1. Stimulus: The presence of a stimulus or trigger activates the body's pain receptors (nociceptors). This stimulus can be physical, such as a cut/burn, or it can be caused by inflammation/pressure.

2. Transmission: Once the nociceptors are activated, they send a signal along nerve fibres to the spinal cord and then up to the brain.

3. Perception: When the pain signal reaches the brain, it is processed and interpreted as a conscious experience of pain. This involves several regions of the brain, including those that identify the location and intensity of the pain, and also the emotional centres of the brain, which process the unpleasantness and emotional impact.

4. Response: Once the pain signal has been processed, the brain generates a response to the pain. This might involve withdrawing from the painful stimulus or seeking medical attention.
