Plica Sublingualis
The sublingual papilla or sublingual fold is a small fold of soft tissue located on each side of the frenulum linguae binding the lips to the gums within the mouth. The sublingual papilla marks the site of the sublingual gland with its major sublingual duct and its minor sublingual ducts opening upon the papilla. Clinical significance In cases of pathology, papillotomy procedures are undertaken for cases of obstructive salivary gland disease Salivary gland diseases (SGDs) are multiple and varied in cause. There are three paired major salivary glands in humans – the parotid glands, the submandibular glands, and the sublingual glands. In addition there are about 800-1000 minor saliv ...s. The appearance of papillae may be influenced by the underlying pathology. Based on the classification proposed by Anicin et al., papilla typology affects the duration of sialendoscope introduction and may influence the frequency of intraoperative complications of sialendoscopy.

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. There are also two other types of salivary glands; they are submandibular and parotid glands. Structure They lie anterior and superior to the submandibular gland and inferior and lateral to the tongue, as well as beneath the mucous membrane of the floor of the mouth. They are bounded laterally by the bone of the mandible and inferolaterally by the mylohyoid muscle. The glands can be felt behind each mandibular canine. Placing one index finger within the mouth and the fingertips of the opposite hand outside it, 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 The sublingual glands are drained by 8-20 excretory ducts called the ducts of Rivinus.Ten Cate's ...

Major Sublingual Duct
The excretory ducts of the sublingual gland are from eight to twenty in number. Of the smaller sublingual ducts (ducts of Rivinus), some join the submandibular duct; others open separately into the mouth, on the elevated crest of mucous membrane (plica sublingualis), caused by the projection of the gland, on either side of the frenulum linguae The frenulum of tongue or tongue web (also lingual frenulum or frenulum linguæ; also fraenulum) is a small fold of mucous membrane extending from the floor of the mouth to the midline of the underside of the tongue. Development The tongue start .... One or more join to form the major sublingual duct (larger sublingual duct, duct of Bartholin), which opens into the submandibular duct.

Salivary Gland Disease
Salivary gland diseases (SGDs) are multiple and varied in cause. There are three paired major salivary glands in humans – the parotid glands, the submandibular glands, and the sublingual glands. In addition there are about 800-1000 minor salivary glands in the mucosa of the mouth. The parotid gland is located in front of each ear, and secretes mostly serous saliva via the parotid duct (Stenson duct) into the mouth, usually opening roughly opposite the maxillary second molar. The submandibular gland is located medial to the angle of the mandible, and it drains its mixture of serous and mucous saliva via the submandibular duct (Wharton duct) into the mouth, usually opening in a punctum located in the floor of mouth. The sublingual gland is located below the tongue, on the floor of the mouth. It drains its mostly mucous saliva into the mouth via about 8-20 ducts which open along the plica sublingualis (a fold of tissue under the tongue). The function of the salivary glands is to se ...
