Foregut
Definition:
(n.) The anterior part of the alimentary canal, from the mouth to the intestine, o/ to the entrance of the bile duct.
Example Sentences:
(1) Foregut cysts are uncommon congenital defects of the developing airway and gut.
(2) Side branches leave the stomatogastric nervous system and form a plexus along the surface of the entire intestinal tract from where 5-HT-immunoreactive fibers supply: all muscle layers of the muscularis; the external dilator muscles of the foregut and probably some somatic muscles, neurohaemal organs and Malpighian tubules (excretory system).
(3) A good correlation between all three techniques in the diagnosis of ileal carcinoid tumour was found, but the immunoperoxidase technique showed greater sensitivity than the Masson-Fontana technique and greater specificity than the Grimelius technique in the diagnosis of foregut and hindgut carcinoid tumours.
(4) These findings--together with histological, histochemical, and ultrastructural observations made in this and in other studies--point to a foregut type of intestinal differentiation for the glands in a majority of glandular peripheral nerve sheath tumors.
(5) The ventrolateral cell population of the cardiac crest is located more medially and shows long-persistent HNK-1 immunoreactivity dorsolateral to the foregut.
(6) After 5 h, most of the radiolabel was detected in the foregut and intestine.
(7) Both the foregut and the oviduct were 100-1000 fold less sensitive than the hindgut, and each of the former organs required more than 10(-8) M to elicit a detectable excitation.
(8) Depending on site of origin, carcinoids are divided into foregut, midgut, and hindgut derivatives with different clinical symptoms.
