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.
1 Μαρ 2014 · Understanding pain and its causes is both interesting and challenging. These important aspects of pain are discussed in this book, which is now in its second revised edition.
Pain is a vital function of the nervous system in providing the body with a warning of potential or actual injury. It is both a sensory and emotional experience, affected by psychological factors such as past experiences, beliefs about pain, fear or anxiety.
• 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
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. Pain defi-nitions are given in Box 1.
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.
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...
