The histological structure of a simple coiled tubular gland includes:
Epithelium: The lining is typically composed of simple cuboidal or columnar epithelial cells. Lumen: The central cavity through which the secretions are released. Basement Membrane: A thin layer of extracellular matrix that supports the epithelial cells.
The coiled nature of the gland allows for a greater surface area within a limited space, thus enhancing its secretory capacity.
