• ureter
  • The pressure gradient magnitude along the ureter wall and the symmetry line had the maximum value around the throat of moving contracted wall which decreased as the peristalsis propagates toward the bladder. (studymode.com)
  • During propagation of the peristalsis toward the bladder, the inlet backward flow region was limited to the areas near symmetry line but the inner ureter backward flow regions extended to the whole ureter contraction part. (studymode.com)
  • The backward flow was vanished after 1.5 seconds of peristalsis propagation start up and after that time the urine flow was forward in the whole ureter length, so reflux is more probable to be present at the beginning of the wall peristaltic motion. (studymode.com)
  • In the absence of peristalsis, the ureter behaves as a nonuniform passively distensible tube and the flow through it may be taken as approximately steady. (studymode.com)
  • diseases
  • See detailed information below for a list of 6 causes of Visible peristalsis , Symptom Checker , including diseases and drug side effect causes. (rightdiagnosis.com)
  • This information refers to the general prevalence and incidence of these diseases, not to how likely they are to be the actual cause of Visible peristalsis. (rightdiagnosis.com)
  • These ground-breaking results are especially promising for medical research: 'The fundamental explanation of the cooperation between organism and microbiome in regulating peristalsis will in future help us to understand the emergence of severe diseases, which arise from disrupted movement of the intestine,' summarized Bosch.

  • smooth muscle
  • Underlying the epithelium is the lamina propria, which contains myofibroblasts, blood vessels, nerves, and several different immune cells, and the muscularis mucosa which is a layer of smooth muscle that aids in the action of continued peristalsis and catastalsis along the gut. (wikipedia.org)
  • Surrounding this is the muscular layer, which comprises both longitudinal and circular smooth muscle that also helps with continued peristalsis and the movement of digested material out of and along the gut. (wikipedia.org)
  • It is considerably shorter in the living body because the intestines, which are tubes of smooth muscle tissue, maintain constant muscle tone, somewhat like a Slinky that maintains itself in a halfway-tense state but can relax in spots to allow for local distention, peristalsis, and so on.

  • compared normal
  • To find out how peristalsis is regulated in the freshwater polyps, the researchers compared normal Hydra which had typical bacterial colonization with those that had their microbiome completely removed with an antibiotic cocktail. (news-medical.net)
  • effect
  • Here, ex vivo organ bath experiment was further performed to study the effect of FC extract on the inhibition of phenylepinephrine (PE) (10 −4 and 10 −3 M) ureteral peristalsis of porcine ureters with several α 1 -adrenergic antagonists (doxazosin, tamsulosin, and terazosin) as experimental controls.

  • Research
  • From these observation the Kiel research team concluded that only the natural Hydra microbiome - characterized by a balance between the bacterial species present - can play an important pacemaker role in peristalsis. (news-medical.net)
  • water
  • Secondary peristalsis was stimulated by rapid intraoesophageal injection of boluses of air and water, and by a five second oesophageal distension with a balloon. (semanticscholar.org)
  • Instead
  • Instead, lymph circulates through peristalsis in the lymph capillaries, as well as valves in the capillaries, compression during contraction of adjacent skeletal muscle, and arterial pulsation. (wikipedia.org)
