Lateral Delineation of the Gastric Body

Description

Viewed from the lateral aspect, the gastric body (corpus ventriculi) occupies the central portion of the stomach between the fundus superiorly and the pyloric antrum inferiorly and distally. The greater curvature sweeps inferoanteriorly, while the lesser curvature forms a shorter superomedial border that leads toward the pyloric canal. Along the external surface, the anterior wall faces anterolaterally and the posterior wall turns posteromedially toward the lesser sac. The gaster reads as a muscular pouch. A lateral delineation of the gastric body is the cleanest way to teach how the corpus transitions into the antrum and pylorus, and why that junction matters in gastric emptying and in endoscopic orientation. Peptic ulcer disease commonly tracks along the lesser curvature and posterior wall, where penetration can involve the pancreas and erosion may endanger the left gastric artery, while ulcers nearer the greater curvature bring the right gastroepiploic arcade into the conversation. Surgeons also think in these contours when mobilizing the stomach, dividing gastroepiploic vessels along the greater curvature during sleeve gastrectomy, and defining resection margins for gastric carcinoma centered in the body. Use this artwork for gross anatomy teaching blocks on the foregut, for operative atlases covering partial gastrectomy, vagotomy, and bariatric approaches, or for patient-facing diagrams explaining where a gastric body tumor or ulcer sits relative to the curvatures. It also fits radiology and endoscopy modules when paired with contrast studies or gastroscopy labeling of the corpus versus antrum. Anatomical accuracy verified by SciePro's Medical Advisory Board.
