Physiology of Pain:
The millions of pain receptors in the body, receiving sensations then taken to the spinal cord is the gray area continued to spinothalamicus tract, next to the cerebral cortex. The mechanism is as follows:
- The flow of the burning pain of the hands of a chemical release Bradykinin, prostaglandins then stimulate the end of the nerve receptors which then helps the transmission of pain from the hand that burned into the brain.
- Impulses delivered to the brain via nerve to the dorsal horn, the spinal cord.
- Messages received by the thalamus as a sensory center in the brain.
- The impulses are sent to corteks where the intensity and location of pain is felt.
- Decrease in pain begins as a signal from the brain, down through the spinal cord.
- In the dorsal horn of chemicals such as endorphins released to reduce pain.
