The salivary glands in many vertebrates including mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. [1] Salivary glands can be classified as serous, mucous, or seromucous (mixed).
The submandibular salivary glands develop later than the parotid glands and appear late in the sixth week of prenatal development. They develop bilaterally from epithelial buds in the sulcus surrounding the sublingual folds on the floor of the primitive mouth. Solid cords branch from the buds and grow posteriorly, lateral to the developing tongue.

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 .
Malignant salivary gland lesions are rare. However, when a tumour extends to the submandibular, sublingual and the minor salivary glands, they tend to be malignant. [13] Distinguishing a malignant lesion from a benign one may be difficult as they both present as painless lesions. [13] A biopsy is crucial in aiding diagnosis. There are common ...
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.
Blockage, whether caused by salivary duct stones or external compression, may cause pain and swelling of the parotid gland . Koplik's spots which are pathognomonic of measles are found near the opening of the parotid duct. The parotid duct may be cannulated by inserting a tube through the internal orifice in the mouth. [2]
