Cardia (histological slide)

The cardia of the stomach is a thin strip of muscle that represents the transition between the esophagus and the stomach and their mucosa. It consists of 4 basic layers, which are characteristic of the general structure of the alimentary canal.

Tunica mucosa[edit | edit source]

Drawing of cardia

Epithelium[edit | edit source]

transition of the stratified squamous epithelium of the esophagus into a single-layered cylindrical mucus-forming - gastroesophageal junction

Lamina propria mucosae[edit | edit source]

sparse collagenous tissue, blood vessels, lymphatic infiltration
glandulae cardiacae – branched tubular mucinous glands, the end parts of which can twist and have a spacious lumen

- their secretory elements produce mucus and lysozyme

- exceptions can be found that exclude HCl

- structurally similar to esophageal cardiac glands

the gastric glands open into wide and shallow pits (foveolae gastricae) that reach approximately 1/4 of the mucosa's height

Lamina muscularis mucosae[edit | edit source]

bundles of smooth muscle cells
usually an inner circular and an outer longitudinal layer

Tunica submucosa[edit | edit source]

sparse collagenous tissue

Tunica muscularis[edit | edit source]

2 layers of muscle

- inner layer - circular

- outer layer - longitudinal

Tunica serosa[edit | edit source]

sparse collagenous tissue
on the surface of the mesothelium - a single-layered flat epithelium
