Male Stomach Layers

Description

A 3D model of the male stomach wall showing all layers in an exploded or dissected view. The mucosa displays its glandular surface with gastric pits, the submucosa contains the submucosal vascular plexus, and the muscularis shows its unique three-layer arrangement: inner oblique, middle circular, and outer longitudinal. The serosa covers the external surface. The stomach is the only GI organ with three muscular layers instead of two. The oblique layer enables the churning motion that mechanically breaks down food. The circular layer concentrates at the pylorus to form the sphincter. The longitudinal layer runs along the curvatures. Stomach wall anatomy is taught in histology and gastroenterology. Understanding the layered structure matters for cancer staging, where depth of invasion through each layer determines the T classification. Medical advisory board reviewed.
