Coloring Image

Histological section of the esophagus stained with H&E, showing its layered structure. The mucosa includes stratified squamous epithelium, lamina propria, and muscularis mucosae composed of smooth muscle. Beneath the mucosa lies the submucosa containing submucosal mucous glands. The muscularis externa consists of skeletal muscle fibers in the upper region, transitioning to smooth muscle in lower regions. The outermost layer is the adventitia. The image illustrates the organization of esophageal layers and associated glandular and muscular components.
