Short Gastric Arteries
The short gastric arteries consist of from five to seven small branches, which arise from the end of the splenic artery, and from its terminal divisions. They pass from left to right, between the layers of the gastrolienal ligament, and are distributed to the greater curvature of the stomach, anastomosing with branches of the left gastric and left gastroepiploic arteries. Unlike the gastroepiploics and the left and right gastric arteries, the short gastric arteries have poor anastomoses if the splenic artery is blocked. Structure The short gastric arteries arise from the splenic artery. They run along part of the greater curvature of the stomach. Function The short gastric arteries supply the fundus of the stomach on the side of the greater curvature of the stomach The curvatures of the stomach refer to the greater and lesser curvatures. The greater curvature of the stomach is four or five times as long as the lesser curvature. Greater curvature The greater curv ...

Celiac Artery
The celiac () artery (also spelled ''coeliac''), also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) in humans, it is one of three anterior/ midline branches of the abdominal aorta (the others are the superior and inferior mesenteric arteries). Structure The celiac artery is the first major branch of the descending abdominal aorta, branching at a 90° angle. This occurs just below the crus of the diaphragm. This is around the first lumbar vertebra. There are three main divisions of the celiac artery, and each in turn has its own named branches: The celiac artery may also give rise to the inferior phrenic arteries. Function The celiac artery supplies oxygenated blood to the liver, stomach, abdominal esophagus, spleen, and the superior half of both the duodenum and the pancreas. These structures correspond to the embryonic foregut. (Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Splenic Artery
In human anatomy, the splenic artery or lienal artery is the blood vessel that supplies oxygenated blood to the spleen. It branches from the celiac artery, and follows a course superior to the pancreas. It is known for its tortuous path to the spleen. Structure The splenic artery gives off branches to the stomach and pancreas before reaching the spleen. Note that the branches of the splenic artery do not reach all the way to the lower part of the greater curvature of the stomach. Instead, that region is supplied by the right gastroepiploic artery, a branch of the gastroduodenal artery. The two gastroepiploic arteries anastomose with each other at that point. Relations The splenic artery passes between the layers of the lienorenal ligament. Along its course, it is accompanied by a similarly named vein, the splenic vein, which drains into the hepatic portal vein. Clinical significance Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Curvature Of The Stomach
The curvatures of the stomach refer to the greater and lesser curvatures. The greater curvature of the stomach is four or five times as long as the lesser curvature. Greater curvature The greater curvature of the stomach forms the lower left or lateral border of the stomach. Surface Starting from the cardiac orifice at the incisura cardiaca, it forms an arch backward, upward, and to the left; the highest point of the convexity is on a level with the sixth left costal cartilage. From this level it may be followed downward and forward, with a slight convexity to the left as low as the cartilage of the ninth rib; it then turns to the right, to the end of the pylorus. Directly opposite the incisura angularis of the lesser curvature the greater curvature presents a dilatation, which is the left extremity of the pyloric part; this dilatation is limited on the right by a slight groove, the sulcus intermedius, which is about 2.5 cm, from the duodenopyloric constriction.

Gastrolienal Ligament
The gastrosplenic ligament (also known as the ''ligamentum gastrosplenicum'' or gastrolienal ligament) is part of the greater omentum extending between the stomach and the spleen. It contains several blood vessels. Structure The gastrosplenic ligament is consist of visceral peritoneum. It extends between the greater curvature of stomach and the hilum of the spleen. Contents It contains the short gastric arteries and veins, and the left gastroepiploic artery and vein. Development Embryonically, the gastrosplenic ligament is derived from the dorsal mesogastrium.

Left Gastric
In human anatomy, the left gastric artery arises from the celiac artery and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus. The left gastric artery anastomoses with the right gastric artery, which runs right to left. Important to note is that the esophageal branch of the left gastric artery ascends and passes through the esophageal hiatus. Clinical significance In terms of disease, the left gastric artery may be involved in peptic ulcer disease: if an ulcer erodes through the stomach mucosa into a branch of the artery, this can cause massive blood loss into the stomach, which may result in such symptoms as hematemesis or melaena.

Left Gastroepiploic Artery
The left gastroepiploic artery (or left gastro-omental artery), the largest branch of the splenic artery, runs from left to right about a finger's breadth or more from the greater curvature of the stomach, between the layers of the greater omentum, and anastomoses with the right gastroepiploic (a branch of the right gastro-duodenal artery originating from the hepatic branch of the coeliac trunk). In its course it distributes: * "Gastric branches": several ascending branches to both surfaces of the stomach; * "Omental branches": descend to supply the greater omentum and anastomose with branches of the middle colic.

Stomach Blood Supply
The stomach is a muscular, hollow organ in the gastrointestinal tract of humans and many other animals, including several invertebrates. The stomach has a dilated structure and functions as a vital organ in the digestive system. The stomach is involved in the gastric phase of digestion, following chewing. It performs a chemical breakdown by means of enzymes and hydrochloric acid. In humans and many other animals, the stomach is located between the oesophagus and the small intestine. The stomach secretes digestive enzymes and gastric acid to aid in food digestion. The pyloric sphincter controls the passage of partially digested food (chyme) from the stomach into the duodenum, where peristalsis takes over to move this through the rest of intestines. Structure In the human digestive system, the stomach lies between the oesophagus and the duodenum (the first part of the small intestine). It is in the left upper quadrant of the abdominal cavity. The top of the stomach lies against ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
