Sublingual gland
The paired sublingual glands are major salivary glands in the mouth. They are the smallest, most diffuse, and the only unencapsulated major salivary glands. They provide only 3-5% of the total salivary volume.〔
==Structure==
They lie anterior to the submandibular gland inferior to the tongue, as well as beneath the mucous membrane of the floor of the mouth. Each gland is effectively palpated on the floor of the mouth posterior to each mandibular canine. Placing one index finger intraorally and the fingertips of the opposite hand extraorally, the compressed gland is manually palpated between the inner and outer fingers.〔Illustrated Anatomy of the Head and Neck, Fehrenbach and Herring, Elsevier, 2012, p. 156〕
They are drained by 8-20 excretory ducts called the ducts of Rivinus.〔Ten Cate's Oral Histology, Nanci, Elsevier, 2013, page 255〕 The largest of all, the sublingual duct (of Bartholin) joins the submandibular duct to drain through the sublingual caruncle. The sublingual caruncle is a small papilla near the midline of the floor of the mouth on each side of the lingual frenum.〔 Most of the remaining small sublingual ducts open separately into the mouth on an elevated crest of mucous membrane, the plica sublingualis, formed by the gland and located on either side of the frenulum linguae.
