The submandibular gland, also known as the submaxillary gland, is a salivary gland located beneath the lower jawbone, producing around 70% of the saliva in the mouth. Synonyms for the submandibular gland include the "submaxillary gland," "glandula submandibularis," and "glandula submaxillaris." Its primary role is to secrete enzymes that aid in the digestion of food and lubricate the mouth to facilitate swallowing and prevent dryness. These synonyms are often used interchangeably by medical professionals and researchers, but it is important to know that they all refer to the same organ and its functions.
