Each acinus consists of a single layer of cuboidal epithelial cells surrounding a lumen, a central opening where the saliva is deposited after being produced by the secretory cells. The three forms of acini are classified in terms of the type of epithelial cell present and the secretory product being produced - serous, mucoserous, and mucous.

The mucous salivary glands are similar in structure to the buccal and labial glands. They are found especially at the back part behind the vallate papillae, but are also present at the apex and marginal parts. In this connection, the anterior lingual glands require special notice.
Seromucous glands (mixed) secrete both protein and mucus. Examples include the salivary glands: although the parotid gland (saliva secretion 25%) is predominantly serous, the sublingual gland (saliva secretion 5%) mainly mucous gland, and the submandibular gland (saliva secretion 70%) is a mixed, mainly serous gland.
At the right is a group of mucous acini, at the left a group of serous acini. Lobes contain smaller lobules, which contain adenomeres , the secretory units of the gland. Each adenomere contains one or more acini , or alveoli, which are small clusters of cells that secrete their products into a duct.
They contain serous acini, a grouping of serous cells that secrete serous fluid, isotonic with blood plasma, that contains enzymes such as alpha-amylase. Serous glands are most common in the parotid gland and lacrimal gland but are also present in the submandibular gland and, to a far lesser extent, the sublingual gland.

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.
