VISCERAL PERCEPTION Visceral perception: sensory transduction in visceral afferents and nutrients
The possible mechanisms that may be involved in nutrient detection in the wall of the gastrointestinal tract are reviewed. There is strong functional and electrophysiological evidence that both intrinsic and extrinsic primary afferent neurones mediate mechanoand chemosensitive responses in the gastrointestinal tract. This review focuses on the extrinsic afferent pathways as these are the ones t...
متن کاملVISCERAL PERCEPTION Visceral perception: inflammatory and non-inflammatory mediators
Visceral hypersensitivity is currently the most widely accepted mechanism responsible for abdominal pain. Inflammatory mediators are known to sensitise primary afferents and to recruit silent nociceptors. Recent evidence suggests that non-inflammatory mediators also have the potential to trigger visceral pain. This sequence of events may constitute part of an alerting system which prompts the c...

متن کاملVISCERAL PERCEPTION Hypersensitivity in functional gastrointestinal disorders
Patients with functional gastrointestinal disorders may have visceral sensory dysfunction so that physiological stimuli induce their symptoms. The clinical significance of altered perception—that is, its relation to clinical symptoms—remains unclear. Data indicate that sensory dysfunction is associated with altered reflex activity. Hence evidence of combined sensory-reflex dysfunction as a comm...
متن کاملColorectal visceral perception in diverticular disease.
BACKGROUND AND AIMS The pathogenesis of asymptomatic diverticular disease (ADD) and symptomatic uncomplicated diverticular disease (SUDD) has not been elucidated. The aim of our study was to assess whether altered visceral perception or abnormal compliance of the colorectal wall play a role in these clinical entities. METHODS Ten ADD patients, 11 SUDD patients, and nine healthy controls were ...
