Gastrointestinal Motility
نویسنده
چکیده
Anatomic regions of the stomach are the fundus, corpus (body), antrum and pylorus. The functional regions of the stomach do not correspond to the anatomic regions. Functionally, the stomach can be divided into the gastric reservoir and the gastric pump (Fig. 1). The gastric reservoir consists of the fundus and corpus. The gastric pump is represented by the area at which peristaltic waves occur: it includes the distal part of the corpus and the antrum. Due to different properties of the smooth muscle cells the gastric reservoir is characterised by tonic activity and the gastric pump by phasic activity.

In vivo and in vitro effects of Salsola collina on gastrointestinal motility in rats
Objective(s): Salsola collina is widely distributed along the Bohai coast and consumed as an edible plant by native residents. We have found surprisingly that S. collina extracts promoted gastrointestinal motility in mice previously. In the present study, effects of S. collina on gastrointestinal motility in rats and its underlying mechanism were explored.<st...
متن کاملGastrointestinal motility disorders: an update.
Gastrointestinal motility disorders encompass a wide array of signs and symptoms that can occur anywhere throughout the luminal gastrointestinal tract. Motility disorders are often chronic in nature and dramatically affect patients' quality of life. These prevalent disorders cause a tremendous impact both to the individual patient and to society as a whole. Significant progress has been made ov...
متن کاملβ1/2 or M2/3 Receptors Are Required for Different Gastrointestinal Motility Responses Induced by Acupuncture at Heterotopic or Homotopic Acupoints
Acupuncture at homotopic acupoints or heterotopic acupoints is known to either inhibit or facilitate gastrointestinal motility, depending on the acupoint location. However, little effort has been made to investigate the roles of specific receptors (such as adrenergic and muscarinic acetylcholine receptors) in mediating the effects of acupuncture at heterotopic and homotopic acupoints. Different...
متن کاملGastrointestinal motility disorders and acupuncture.
During the last decades, numerous studies have been performed to investigate the effects and mechanisms of acupuncture or electroacupuncture (EA) on gastrointestinal motility and patients with functional gastrointestinal diseases. A PubMed search was performed on this topic and all available studies published in English have been reviewed and evaluated. This review is organized based on the gas...
متن کاملAlteration of antral and proximal colonic motility induced by chronic psychological stress involves central urocortin 3 and vasopressin in rats.
Because of the difficulties in developing suitable animal models, the pathogenesis of stress-induced functional gastrointestinal disorders is not well known. Here we applied the communication box technique to induce psychological stress in rats and then examined their gastrointestinal motility. We measured upper and lower gastrointestinal motility induced by acute and chronic psychological stre...
متن کاملHuman prokinetic drugs promote gastrointestinal motility in zebrafish.
BACKGROUND Gastrointestinal (GI) motility disorders are highly prevalent in populations worldwide and the development of effective and safe drug treatments for GI motility disorders has proven challenging. In this study, taking advantage of the transparency of larval zebrafish, we developed a novel zebrafish GI motility model for drug screening and efficacy assessment. METHODS Zebrafish at 5 ...
