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 .
Salivary gland dysfunction refers to either xerostomia (the symptom of dry mouth) or salivary gland hypofunction (reduced production of saliva); it is associated with significant impairment of quality of life. [34] Following radiotherapy of the head and neck region, salivary gland dysfunction is a predictable side-effect. [34]
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.
There are three pairs of main salivary glands and between 800 and 1,000 minor salivary glands, all of which mainly serve the digestive process, and also play an important role in the maintenance of dental health and general mouth lubrication, without which speech would be impossible. [11] The main glands are all exocrine glands, secreting via ...
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.
Striated duct in parotid gland. A striated duct (Pflüger's ducts) is a gland duct which connects an intercalated duct to an interlobular duct. It is characterized by the basal infoldings of its plasma membrane, characteristic of ion-pumping activity by the numerous mitochondria.
The preauricular deep parotid lymph nodes (anterior auricular glands or preauricular glands), from one to three in number, lie immediately in front of the tragus.. Their afferents drain multiple surfaces, most of which are lateral in origin.
It is a complication of surgery involving the parotid gland whereby injury to these branches, which innervate the parotid gland and sweat glands of the face respectively, form abnormal connections. Salivation leads to perspiration and flushing of the pre-auricular region and is called 'gustatory sweating'.
