Initially the foregut, midgut, and hindgut are in extensive contact with the mesenchyme of the posterior abdominal wall. By the fifth week, the connecting tissue bridge has narrowed, and the caudal part of the foregut, the midgut, and a major part of the hindgut are suspended from the abdominal wall by the dorsal mesentery, which extends from ...
The foregut arises from the endoderm, developing from the folding primitive gut, and is developmentally distinct from the midgut and hindgut. Although the term “foregut” is typically used in reference to the anterior section of the primitive gut, components of the adult gut can also be described with this designation. Pain in the epigastric ...
The midgut is the portion of the human embryo from which most of the intestines develop. After it bends around the superior mesenteric artery, it is called the "midgut loop". It comprises the portion of the alimentary canal from the end of the foregut at the opening of the bile duct to the hindgut, about two-thirds of the way through the ...
Foregut: esophagus to first 2 sections of the duodenum: Esophagus, stomach, duodenum (1st and 2nd parts), liver, gallbladder, pancreas, superior portion of pancreas (Though the spleen is supplied by the celiac trunk, it is derived from dorsal mesentery and therefore not a foregut derivative) celiac trunk Midgut
The hindgut (or epigaster) is the posterior part of the alimentary canal. In mammals, it includes the distal one third of the transverse colon and the splenic flexure, the descending colon, sigmoid colon and up to the ano-rectal junction. In zoology, the term hindgut refers also to the cecum and ascending colon.
The foregut is supplied by the celiac trunk, the midgut is supplied by the superior mesenteric artery (SMA), and the hindgut is supplied by the inferior mesenteric artery (IMA). This division is established by the fourth week of development. After this, the midgut undergoes a period of rapid elongation, forcing it to herniate through the navel.
Next, thrust in an inward and upward motion on the diaphragm. This will force air out of the lungs and remove the blockage. Repeat these abdominal thrusts up to five times, the doctor advised.
The final branch which is important for the digestive system is the inferior mesenteric artery, which supplies the regions of the digestive tract derived from the hindgut, which includes the distal 1/3 of the transverse colon, descending colon, sigmoid colon, rectum, and the anus above the pectinate line.
