The curvatures of the
Greater curvature
The greater curvature of the stomach forms the lower left or lateral border of the stomach.[3]
Surface
Starting from the
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.
The portion between the sulcus intermedius and the duodenopyloric constriction is termed the
At its commencement the greater curvature is covered by peritoneum continuous with that covering the front of the organ.
The left part of the curvature gives attachment to the
Blood supply
There are three arteries which primarily supply the greater curvature:
- short gastric arteries — upper part
and the gastroepiploic vessels:
- gastric branches of left gastro-omental artery— middle part
- gastric branches of right gastro-omental artery— lower part
Lesser curvature
The lesser curvature of the stomach forms the upper right or medial border of the stomach.[3]
Structure
The lesser curvature of the stomach travels between the
Nearer its pyloric than its cardiac end is a well-marked notch, the incisura angularis, which varies somewhat in position with the state of distension of the viscus; it serves to separate the stomach into a right and a left portion.
The lesser curvature gives attachment to the two layers of the
