Magnetic Resonance Imaging of Alimentary Tract Development in Manduca sexta

Non-invasive 3D magnetic resonance imaging techniques were used to investigate metamorphosis of the alimentary tract of Manduca sexta from the larval to the adult stage. The larval midgut contracts in volume immediately following cessation of feeding and then greatly enlarges during the late pharate pupal period. Magnetic resonance imaging revealed that the foregut and hindgut of the pharate pu...

Alimentary Tract: Intestine

While tremendous advances have improved the understanding of inflammatory bowel disease, with regard to environmental risk factors as well as the biochemical nature of the inflammatory process, a determination of primary etiology remains elusive. Numerous theories have been proposed in the past century concerning the cause of Crohn’s disease and ulcerative colitis with implications for specific...

Alimentary Tract Motility

Alimentary/Tract/Motility/ 1 SMOOTH MUSCLE Smooth muscle lines the walls of hollow organs (eg. intestine, uterus), the circulatory system (arteries and veins), and ducts of secretory glands. The primary role of smooth muscle is to regulate the diameter of the organ lumen which it surrounds. Although "smooth muscle" is used to categorize muscle components of these various tissues, there is a lar...
