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.
They are situated just superficial to the submandibular salivary gland, and posterolateral to the anterior belly of either digastric muscle. [1]One gland, the middle gland of Stahr, which lies on the facial artery as it turns over the mandible, is the most constant of the series; small lymph glands are sometimes found on the deep surface of the submandibular gland.
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%.

Salivary glands, such as the submandibular gland or parotid gland, can become blocked by salivary stones. Dr. Lee says this can block the natural flow of saliva, causing facial swelling and pressure.
Sialolithiasis refers to the formation of calculi within a salivary gland. If a calculus forms in the duct that drains the saliva from a salivary gland into the mouth, then saliva will be trapped in the gland. This may cause painful swelling and inflammation of the gland. Inflammation of a salivary gland is termed sialadenitis. Inflammation ...
The most common cause of enlargement of the submental lymph nodes are infections (including viral infections (mononucleosis, Epstein-Barr virus infection, and cytomegaloviral infections), toxoplasmosis, and dental infections (e.g. periodontitis)).
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]
Infections involving the salivary glands can be viral or bacterial (or rarely fungal). Mumps is the most common viral sialadenitis. It usually occurs in children and involves pain in front of the ear, swelling of the parotid, fever, chills, and headaches. [2] Bacterial sialadenitis is usually caused by ascending organisms from the mouth.
