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.
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.
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.
• The modulation of pain involves changing or inhibiting transmission of pain impulses in the descending pathways of the spinal cord. • Modulation leads to either an increase in the transmission of pain impulses (excitatory) or a decrease in transmission (inhibition).
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.
1 Σεπ 2018 · This chapter reviews the physiology and mechanisms of pain, as well as the pathways in the central and peripheral nervous system that transmit nociceptive information. The chapter divides the pain anatomical pathways into the peripheral nervous system, the spinal cord with the medullary dorsal horn system, and the ascending and supraspinal system.
• 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
