Research into basic mechanisms underlying pain is an increasingly exciting and promising area. However, most of what is known about the anatomy and physiology of pain is from studies of experimentally induced cutaneous (skin) pain, while most clinical pain arises from deep tissues.
This article provides an overview of the physiological mechanisms of pain and the important pain pathways. We will discuss pain receptors, transmission of pain signals to the spinal cord and pain pathways within the spinal cord. We will also look at how pain can be modulated at different levels along the pathway.
The anatomy and physiology of pain. Charlotte E Steeds. Abstract. Pain is an unpleasant experience that results from both physical and psychological responses to injury. A complex set of pathways trans-mits pain messages from the periphery to the central nervous system, where control occurs from higher centres.
• Pain is an unpleasant sensation which warns of impending tissue damage. • Pain develops as a results of chemical, thermal or mechanical stimuli. • Activation of A-δ and C fi bres occurs; these are known as nociceptors and
5 Μαΐ 2018 · The pain pathways form a complex, dynamic, sensory, cognitive, and behavioral system that evolved to detect, integrate, and coordinate a pro-tective response to incoming noxious stimuli that threatens tissue injury or organism survival.1 This defense system includes both the primitive spinal reflexes that are the only protection for simple organ...
Pain is a complex experience, initiated by sensory information conveyed from a noxious stimulus, greatly modified by affective (i.e. emotional), cultural and cognitive perspectives.
