pain signaling

Pain signaling involves the nervous system detecting damage or potential harm to the body. When tissue is injured, specialized cells send signals through nerves to the spinal cord and brain. These signals trigger the sensation of pain, alerting us to take action and prevent further injury. The nerves act like messengers, transmitting information quickly to ensure a rapid response. Once the brain processes these signals, it interprets them as pain, guiding behaviors like withdrawal or seeking help. This system helps protect our body by making us aware of harmful stimuli so we can respond appropriately.
