The lesser curvature of the stomach forms the upper right or medial border of the stomach. [3] The lesser curvature of the stomach travels between the cardiac and pyloric orifices . It descends as a continuation of the right margin of the esophagus in front of the fibers of the right crus of the diaphragm , and then, turning to the right, it ...
The hepatogastric ligament or gastrohepatic ligament connects the liver to the lesser curvature of the stomach. It contains the right and the left gastric arteries. In the abdominal cavity, it separates the greater and lesser sacs on the right. It is sometimes cut during surgery in order to access the lesser sac.
Small intestine may loop through a perforation in the gastrosplenic ligament, ending lateral to the spleen and stomach. [1] This is known as gastrosplenic ligament entrapment , and is usually caused by abdominal trauma . [ 4 ]
The angular incisure (or angular notch) is a small notch on the stomach. It is located on the lesser curvature of the stomach near the pyloric end. Its location varies depending on how distended the stomach is. [1] The angular incisure is used as a separation point between the right and left portions of the stomach, the body and the pylorus. [2]
The lesser sac is divided into two "omenta": The lesser omentum (or hepatogastric) is attached to the lesser curvature of the stomach and the liver. [5] The greater omentum (or gastrocolic) hangs from the greater curvature of the stomach and loops down in front of the intestines before curving back upwards to attach to the transverse colon. [5]
In human anatomy, the left gastric artery arises from the celiac artery and runs along [1] the superior portion of [citation needed] the lesser curvature of the stomach before anastomosing with the right gastric artery (which runs right to left [citation needed]).
The anterior gastric branches of anterior vagal trunk are branches of the anterior vagal trunk which supply the stomach. [1]One long branch of it runs from the lesser curvature or parallel to it in lesser omentum as far as the pyloric antrum to fan out into branches in a way like the digits of a crow's foot to supply the pyloric antrum and the anterior wall of pyloric canal.
The right gastric vein passes right along the lesser curvature of the stomach to the pylorus. [1] [2] Once there, it joins onto the portal vein before the duodenum.[1] [2] The prepyloric vein is the last connecting branch onto the right gastric vein, marking the end of the stomach, and draining the proximal part of the duodenum.
