The components like lysozyme, lactoferrin, salivary peroxidase, myeloperoxidase, and thiocyanate concentrations act as a defense mechanism in the saliva. Saliva is secreted from 3 pairs of major salivary glands (parotid, submandibular, sublingual) alongside many minor salivary glands.
The sublingual glands are a pair of major salivary glands located inferior to the tongue, anterior to the submandibular glands. [6] The secretion produced is mainly mucous in nature, but it is categorized as a mixed gland. [ 8 ]
The parotid glands are a pair of mainly serous salivary glands located below and in front of each ear canal, draining their secretions into the vestibule of the mouth through the parotid duct. [3] Each gland lies behind the mandibular ramus and in front of the mastoid process of the temporal bone .
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 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.
There are three sets of salivary glands: the parotid, the submandibular and the sublingual glands. The glands secrete saliva for proper mixing of food and provides enzymes to start chemical digestion. Saliva helps to hold together the formed bolus which is swallowed after chewing.
Floor of the mouth with lingual frenum and sublingual fold. The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. [3] The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces.
The site of the incision is extra-oral, and usually made 2–3 cm below, and parallel to, the inferior border of the mandible. Ludwig's angina is a serious infection involving the submandibular, sublingual and submental spaces bilaterally. [3] Ludwig's angina may extend into the pharyngeal and cervical spaces, and the swelling can compress the ...
