pyloric mucosa

Definition: The antral mucosa (Synonym: pyloric mucosa) is the mucosa found in the gastric antrum.

Its characteristic feature is presence of coiled and branching antral glands.

These are lined by mucus cells that are interspersed with endocrine cells (chiefly G and D types), and a few parietal cells.

The parietal cells are most numerous proximally near the oxynto-antral border.

The foveolar component is taller in the antral mucosa than in the oxyntic mucosa.
