Sialadenitis (sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands. [2]
Though the parotid gland is the largest, it provides only 25% of the total salivary volume. The serous cell predominates in the parotid, making the gland secrete a mainly serous secretory product. [10] The parotid gland also secretes salivary alpha-amylase (sAA), which is the first step in the decomposition of starches during mastication. It is ...
HIV parotitis: Generalized lymphadenopathy has long been associated with HIV, but the localized enlargement of the parotid gland is less well known. [citation needed] HIV-associated salivary gland disease can involve many diseases but often presents as enlargement of the parotid gland and a dry mouth. Causes have not been specifically ...
Sialodochitis (also termed ductal sialadenitis), [1] is inflammation of the duct system of a salivary gland. [2] This is compared to sialadenitis, which is inflammation of the gland parenchyma. [3] Sialodochitis may be associated with salivary duct strictures and salivary stones. [4] It is common in both the parotid glands and submandibular ...
Sialadenitis is inflammation of the salivary glands, which may cause acinar atrophy and create an appearance known as "pruning of the tree" on a sialogram, where there are less branches visible from the duct system. A space occupying lesion that occurs within or adjacent to a salivary gland can displace the normal anatomy of the gland.
Picture of the mouth showing the sublingual caruncle and related anatomical structures The submandibular duct arises from deep part of submandibular gland , a salivary gland . It begins by numerous branches from the superficial surface of the gland, and runs forward between the mylohyoid , hyoglossus , and genioglossus muscles .
The parotid duct is formed when several interlobular ducts, the largest ducts inside the parotid gland, join.It emerges from the parotid gland. It runs forward along the lateral side of the masseter muscle for around 7 cm. [2] In this course, the duct is surrounded by the buccal fat pad.
The salivary glands in many vertebrates including mammals are exocrine glands that produce saliva through a system of ducts. Humans have three paired major salivary glands (parotid, submandibular, and sublingual), as well as hundreds of minor salivary glands. [1] Salivary glands can be classified as serous, mucous, or seromucous (mixed).
