Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Visceral structures are highly sensitive to distension (stretch), ischemia and inflammation, but relatively insensitive to other stimuli that normally evoke pain such as cutting or burning.
In the abdomen, general visceral afferent fibers usually accompany sympathetic efferent fibers. This means that a signal traveling in an afferent fiber will begin at sensory receptors in the afferent fiber's target organ, travel up to the ganglion where the sympathetic efferent fiber synapses, continue back along a splanchnic nerve from the ganglion into the sympathetic trunk, move into a ...
As a functional disorder, there is, by definition, no known disease process affecting the structure of the body, yet the person experiences symptoms relating to their body function. Symptoms of functional neurological disorders are clinically recognisable, but are not categorically associated with a definable organic disease. [1] [2]
In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders the older term somatoform (DSM-IV) has been replaced by somatic symptom disorder, which is a disorder characterised by persistent somatic (physical) symptoms, and associated psychological problems to the degree that it interferes with daily functioning and causes ...
Functional somatic syndrome (FSS) is any of a group of chronic diagnoses with no identifiable organic cause.This term was coined by Hemanth Samkumar. [citation needed] It encompasses disorders such as fibromyalgia, chronic widespread pain, temporomandibular disorder, irritable bowel syndrome, [1] lower back pain, tension headache, atypical face pain, non-cardiac chest pain, insomnia ...
These fibers, categorized as C fibers and small Aδ fibers, are present in skin, peripheral nerves, and organs. [1] The role of these nerves is to innervate some skin sensations (somatic afferents) and help control autonomic function (autonomic fibers). It is estimated that 15–20 million people in the United States have some form of ...
The distinction between special and general senses is used to classify nerve fibers running to and from the central nervous system – information from special senses is carried in special somatic afferents and special visceral afferents.
Nociplastic pain is a longterm complex pain, one of three mechanisms of pain, defined by the International Association for the Study of Pain as "pain that arises from altered nociception despite no clear evidence of actual or threatened tissue damage causing the activation of peripheral nociceptors or evidence for disease or lesion of the somatosensory system causing the pain".
