Salivary glands can be classified as serous, mucous, or seromucous (mixed). In serous secretions , the main type of protein secreted is alpha-amylase , an enzyme that breaks down starch into maltose and glucose , [ 2 ] whereas in mucous secretions , the main protein secreted is mucin , which acts as a lubricant .
Further, because the secretory cells are of both serous and mucous types, the submandibular gland is a mixed gland, and though most of the cells are serous, the exudate is chiefly mucous. It has long striated ducts and short intercalated ducts. [7] The secretory acinar cells of the submandibular gland have distinct functions.
Mucoserous acini (singular acinus) or mixed acini are mainly present in submandibular and sublingual glands. They are formed by mucous cells with some serous cells interspersed each other. Both cells pour their secretion directly in the lumen. Layer of mucous cells and serous demilune of serous cells superficial to mucous cells
The sublingual gland (glandula sublingualis) is a seromucous polystomatic exocrine gland.Located underneath the oral diaphragm (diaphragma oris), the sublingual gland is the smallest and most diffuse of the three major salivary glands of the oral cavity, with the other two being the submandibular and parotid.
Serous glands secrete a watery, often protein-rich, fluid-like product, e.g. sweat glands. Mucous glands secrete a viscous product, rich in carbohydrates (such as glycoproteins), e.g. goblet cells. Sebaceous glands secrete a lipid product. These glands are also known as oil glands, e.g. Fordyce spots and meibomian glands.

Mucous glands, also known as muciparous glands, are found in several different parts of the body, and they typically stain lighter than serous glands during standard histological preparation. Most are multicellular, but goblet cells are single-celled glands.
