In human anatomy, the superior epigastric artery is a terminal [1] branch of the internal thoracic artery that provides arterial supply to the abdominal wall, and upper rectus abdominis muscle. It enters the rectus sheath to descend upon the inner surface of the rectus abdominis muscle. It ends by anastomosing with the inferior epigastric artery.
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum. It also indirectly supplies the pancreatic head (via the anterior and posterior superior pancreaticoduodenal arteries).
Schematic image of the blood supply to the human stomach: left and right gastric artery, left and right gastroepiploic artery and short gastric arteries [15] The lesser curvature of the human stomach is supplied by the right gastric artery inferiorly and the left gastric artery superiorly, which also supplies the cardiac region.
Distal to this point (the midgut) the arterial supply is from the superior mesenteric artery (SMA), and its branch the inferior pancreaticoduodenal artery supplies the 3rd and 4th sections. The superior and inferior pancreaticoduodenal arteries (from the gastroduodenal artery and SMA respectively) form an anastomotic loop between the celiac ...
The greater curvature of the stomach forms the lower left or lateral border of the stomach. [3] Starting from the cardiac orifice it begins at the cardiac notch, forming an arch backward, upward, and to the left. A horizontal plane across from the cardiac notch encloses an area called the fundus of the stomach.
The superior mesenteric vessels are composed of the superior mesenteric artery and the superior mesenteric vein.. In human anatomy, the superior mesenteric artery arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
The short gastric arteries are 5-7 small branches of the splenic artery [1] that pass along part of the greater curvature of the stomach [2] from left to right between the layers of the gastrosplenic ligament, and are distributed to the greater curvature of the stomach.
The mesenteric arteries take blood from the aorta and distribute it to a large portion of the gastrointestinal tract. Both the superior and inferior mesenteric arteries arise from the abdominal aorta. [1] Each of these arteries travel through the mesentery, within which they branch several times before reaching the gut. In humans, many of these ...
