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%.

The most common causes of enlargement of the submandibular lymph nodes are infections of the head, neck, ears, eyes, nasal sinuses, pharynx, and scalp. [1] The lymph glands may be affected by metastatic spread of cancers of the oral cavity, anterior portion of the nasal cavity, soft tissues of the mid-face, and submandibular salivary gland. [1]
The submental lymph nodes (or suprahyoid lymph nodes [citation needed]) are 2-3 lymph nodes [1] situated in the submental triangle, [1] between the anterior bellies of the digastric muscle and the hyoid bone. [2]
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 ...
A mucous membrane – the oral mucosa, lines the sides and under surface of the tongue to the gums, and lines the inner aspect of the jaw . It receives secretions from the submandibular and sublingual salivary glands.
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.
A hump of tissue near the base of the tongue houses a series of saliva gland ducts. The two largest ducts are called Wharton's Ducts and they empty the submandibular (submaxillary) and sublingual salivary glands into a small prominence on either side of the frenulum, the sublingual caruncle .
The sublingual salivary glands appear in the eighth week of prenatal development, two weeks later than the other two major salivary glands. They develop from epithelial buds in the sulcus surrounding the sublingual folds on the floor of the mouth, lateral to the developing submandibular gland. These buds branch and form into cords that canalize ...
