👉 Pain fluid, also known as nociceptin or bradykinin, is a substance released by the body in response to tissue damage or potential harm. It plays a crucial role in the inflammatory process by sensitizing nerve endings, thereby amplifying pain signals to the brain. This fluid is part of the body's natural defense mechanism, helping to alert individuals to injuries or infections. It works by binding to specific receptors on nerve cells, leading to increased neuronal excitability and the perception of pain. Pain fluid is not a single molecule but rather a complex mixture, including bradykinin, prostaglandins, and other inflammatory mediators, all contributing to the pain response.
