Anatomic and Physiologic Principles of Pain
Pain is the most frequent cause of suffering and disability and is the most common reason that people seek medical attention. It is a major symptom in many medical conditions, significantly interfering with a person’s quality of life and general functioning. To understand the physiology and the mechanism of pain as well as optimal methods of control, one must appreciate the anatomical pathways that transmit nociceptive information to the brain. For a better comprehension of the anatomical pathways we divided it into four parts: the peripheral system, the spinal and medullary dorsal horn system, and the ascending and supraspinal system.
