PeristalsisAcute esophageal necrosisAnorectal manometryEsophageal motility disorder: An esophageal motility disorder is any medical disorder causing difficulty in swallowing, regurgitation of food and a spasm-type pain which can be brought on by an allergic reaction to certain foods. The most prominent one is dysphagia.Ureteroureterostomy: Ureteroureterostomy ( "urétero-uréte-róstomy") is end-to-end connection (anastomosis) of the two portions of a transected ureter; also called ureteroureteral anastomosis and van Hook operation (after Weller van Hook, surgeon).http://www.Transpulmonary pressure: Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients.AchalasiaMuscle contraction: Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not mean muscle shortening because muscle tension can be produced without changes in muscle length such as holding a heavy book or a dumbbell at the same position.Air sensitivity: Air sensitivity is a term used, particularly in chemistry, to denote the reactivity of chemical compounds with some constituent of air. Most often, reactions occur with atmospheric oxygen (O2) or water vapor (H2O),Handling and Storage of Air-Sensitive Reagents, Technical Bulletin AL-134, Sigma-Aldrich although reactions with the other constituents of air such as carbon monoxide (CO), carbon dioxide (CO2), and nitrogen (N2) are also possible.A. N. Hartley: Annie Norah Hartley (1902 – 1994), usually known simply as Norah Hartley, was a dog breeder and the first female board member of the Kennel Club.Abdominal reflex: An abdominal reflex is a superficial neurological reflex stimulated by stroking of the abdomen around the umbilicus. It can be helpful in determining the level of lesion in a neurology case.Neurogastroenterology: Neurogastroenterology encompasses the study of the brain, the gut, and their interactions with relevance to the understanding and management of gastrointestinal motility and functional gastrointestinal disorders. Specifically, neurogastroenterology focuses on the functions, malfunctions, and the malformations of the sympathetic, parasympathetic, and enteric divisions of the digestive tract.SennaStretta procedure: Stretta is a minimally invasive endoscopic procedure for the treatment of gastroesophageal reflux disease (GERD). A catheter is used to deliver radiofrequency energy to the lower esophageal sphincter, muscle and gastric cardia.SunifiramCatenane: thumbnail|230px|Schematic animation of the template-directed synthesis of the bis-bipyridinium cyclophane / para-phenylene crown ether catenane described in the text.Gastrointestinal physiology: Gastrointestinal physiology is a branch of human physiology addressing the physical function of the gastrointestinal (GI) system. The major processes occurring in the GI system are that of motility, secretion, regulation, digestion and circulation.Hiatus herniaNissen fundoplicationEsophageal disease: Esophageal diseases can derive from congenital conditions, or they can be acquired later in life.Withdrawal reflex: The withdrawal reflex (nociceptive or flexor withdrawal reflex) is a spinal reflex intended to protect the body from damaging stimuli. It is polysynaptic, causing stimulation of sensory, association, and motor neurons.DeramciclaneBarium sulfate suspension: Barium sulfate suspension is barium sulfate powder turned into a liquid form by suspending it in a quick-flowing drink to aid in CT scans of the gastrointestinal region.
