Salivary glands are a group of exocrine glands that secrete saliva into the oral cavity. There are three pairs of major salivary glands: the parotid glands, submandibular glands, and sublingual glands. The parotid glands are located in front of the ears, the submandibular glands are situated below the lower jaw, and the sublingual glands are located under the tongue. There are also numerous minor salivary glands scattered throughout the oral cavity. Saliva produced by the salivary glands contains enzymes such as amylase that initiate the breakdown of food in the mouth, lubricants that aid in swallowing, and antimicrobial agents that help to protect against infection. Saliva also helps to maintain the pH of the oral cavity and is involved in taste perception. Salivary gland disorders can result in a range of symptoms, including dry mouth, difficulty eating and swallowing, and pain or swelling in the affected gland.
