Salivary glands produce saliva, which moistens the mouth to help a person chew and swallow food. Saliva also contains substances (enzymes) that begin the breakdown of food. There are four pairs of salivary glands: 1  The parotid glands are located between the ear and the jaw. 2  The submandibular glands are located under the jaw. 3  The sublingual glands are located on the floor of the mouth under the tongue. 4  The buccal glands are not shown in this picture.
Acini in the parotid glands are almost exclusively of the serous type, while those in the sublingual glands are predominantly mucus cells. In the submaxillary glands, it is common to observe acini composed of both serous and mucus epithelial cells.ost animals have three major pairs of salivary glands that differ in the type of secretion they produce: 1  parotid glands produce a serous, watery secretion. 2  submaxillary (mandibular) glands produce a mixed serous and mucous secretion. 3  sublingual glands secrete a saliva that is predominantly mucous in character.
