C. Glandular epithelium 1. usually simple cuboidal or columnar; 2. Function = secretion; 3. Two major types: a. Exocrine glands secrete products into a duct which opens onto: ° an external surface (i.e sweat gland) or ° an internal space (i.e. gastric gland); b.
The cells of the glandular epithelium are a sheet epithelium continuous with the sheet epithelium lining the organ and the secretions of the cells are released from the apical surface. Examples: sweat glands, salivary glands, pancreas b.
Glandular epithelium is specialized for the production and secretion of products. The cells that form glands are usually cuboidal or columnar in shape.
