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%.

An intralobular duct is the portion of an exocrine gland inside a lobule, leading directly from acinus to an interlobular duct (between lobules). It is composed of two subdivisions, the intercalated duct and the striated duct. In the human mammary gland, the intralobular duct is a part of the glandular system that resides within the lobules.
Serous demilunes, also known as Crescents of Giannuzzi or Demilunes of Heidenhain, are cellular formations in the shape of a half-moon (hence the name "demilune") on the mixed submandibular and sublingual salivary glands. [1] Serous demilunes are the serous cells at the distal end of mucous acini, the secretory endpieces of certain salivary ...
Salivary gland dysfunction refers to either xerostomia (the symptom of dry mouth) or salivary gland hypofunction (reduced production of saliva); it is associated with significant impairment of quality of life. [34] Following radiotherapy of the head and neck region, salivary gland dysfunction is a predictable side-effect. [34]
A salivary duct is a duct which brings saliva from a salivary gland to part of the digestive tract. In human anatomy there are: Parotid duct; Submandibular duct;
Heart disease is the No. 1 cause of death in the U.S. Yet, according to the American Heart Association, half of Americans are unaware of this sobering statistic. The good news is that a diet ...
Sometimes the buccal space is reported to be the most commonly involved fascial space by dental abscesses, [2] although other sources report it is the submandibular space. [1] Infections originating in either maxillary or mandibular teeth can spread into the buccal space, usually maxillary molars (most commonly) and premolars or mandibular ...
