|
Tissue reparative process |
1. Transduction -noxious stimulus cause cell damage -serotonin, bradykinin and histamine activate nociceptors -action potential 2. Transmission -action potential continues from Injury site - spinal cord - brain stem - cortex for processing 3. Perception -conscious experience of pain 4. Modulation -neurons in brainstem move to spinal cord -release substance to inhibit norciceptive impulse |
