Gastrodermis (from Ancient Greek: γαστήρ, gastḗr, "stomach"; δέρμα, dérma, "skin") is the inner layer of cells that serves as a lining membrane of the gastrovascular cavity in cnidarians. [1] It is distinct from the outer epidermis and the inner dermis and is primarily associated with the ventral side of cnidarians.

Enterochromaffin-like cells (ECLs), found in the oxyntic glands release histamine , which also is a powerful stimulant of the acid secretion.
