The submandibular duct (also Wharton's duct or historically submaxillary duct) is one of the salivary excretory ducts. It is about 5 cm long, and its wall is much thinner than that of the parotid duct. It drains saliva from each bilateral submandibular gland and sublingual gland to the sublingual caruncle in the floor of the mouth.
The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth.In adult humans, they each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as parotid gland secretion rises to 50%.

Sialolithiasis (also termed salivary calculi, [1] or salivary stones) [1] is a crystallopathy where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed "Wharton's duct"). Less commonly the parotid gland or rarely the sublingual gland or a minor salivary gland may develop ...
The submandibular glands (previously known as submaxillary glands) are a pair of major salivary glands located beneath the lower jaws, superior to the digastric muscles. [6] The secretion produced is a mixture of both serous fluid and mucus , and enters the oral cavity via the submandibular duct or Wharton duct. [ 7 ]
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 sublingual salivary gland. Saliva from the sublingual gland drains through several small excretory ducts in the floor of the mouth. Sometimes a more distinctive duct can be recognized, known as Bartholin's duct. the deep part of the submandibular gland and the submandibular duct (Wharton's duct) some extrinsic tongue muscle fibers.
Salivary gland atresia is congenital blockage or absence of the orifice of a major salivary gland duct or part of the duct itself. [1] It is a very rare condition. [1] [2] The submandibular salivary gland duct is usually involved, having failed to cannulate during embryological development. The condition first becomes apparent in the first few ...
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.
