    Study Notes

    Stomach Planes and Abdominal Regions

    • The stomach is divided into horizontal and vertical planes
    • Horizontal planes: Transpyloric Plane (subcostal plane) at R9 - L1 and Intertubercular Plane at L5
    • Vertical planes: 2 Mid Clavicular Lines
    • 9 abdominal regions: right hypochondriac, left hypochondriac, right lumbar, left lumbar, right iliac, left iliac, epigastric, umbilical, and hypogastric regions

    Stomach Location and Structure

    • The stomach is an intraperitoneal digestive organ located between the esophagus and the duodenum
    • It has a ‘J’ shape, with a lesser and greater curvature
    • The anterior and posterior surfaces are smoothly rounded with a peritoneal covering

    Parts of the Stomach

    • Cardia: surrounds the superior opening of the stomach at the T11 level
    • Fundus: the rounded, often gas-filled portion superior to and left of the cardia
    • Body: the large central portion inferior to the fundus
    • Pylorus: connects the stomach to the duodenum, divided into the pyloric antrum, pyloric canal, and pyloric sphincter

    Curvatures of the Stomach

    • Greater curvature: forms the long, convex, lateral border of the stomach
    • Lesser curvature: forms the shorter, concave, medial surface of the stomach

    Peritoneal Attachments

    • Lesser omentum: attaches the liver to the lesser curvature
    • Greater omentum: attaches the greater curvature to the posterior body wall

    Surfaces of the Stomach

    • Anterosuperior surface: related to the left lobe of the liver, diaphragm, ant. abdominal wall, and 7, 8, 9 ribs
    • Posteroinferior surface (stomach bed): related to the spleen, Lt. kidney, Lt. suprarenal gland, pancreas, left colic flexure, splenic artery, and diaphragm

    Blood Supply

    • Left gastric artery: supplies the lesser curvature
    • Right gastric artery: supplies the lesser curvature
    • Right gastroepiploic artery: supplies the greater curvature
    • Short gastric arteries: supply the fundus
    • Cystic artery: a branch of the hepatic artery

    Nerve Supply

    • Sympathetic nerves: derived from the spinal cord, via the greater splanchnic nerves, coeliac and hepatic plexuses
    • Parasympathetic nerves: derived from the vagi through gastric nerves
