The parotid gland (often simply "parotid") is a major salivary gland in many animals. In humans, the two parotid glands occur under the mouth and in front of both ears. They are the largest of the salivary glands. Each parotid is wrapped around the mandibular ramus, and secretes saliva through the Stensen duct (or parotid duct) into the mouth, to facilitate mastication and swallowing and to begin the digestion of starches.
The word parotid (paraotic) literally means "beside the ear".
The parotid glands are a pair of mainly serous salivary glands located inferior and anterior to the external acoustic meatus, draining their secretions into the vestibule of oral cavity through the Stensen duct or parotid duct. Each gland lies posterior to the mandibular ramus and anterior to the mastoid process of temporal bone. The gland is effectively palpated bilaterally. Start anterior to each ear, move to the cheek area, and then inferior to the angle of the mandible. The gland is roughly wedge-shaped when seen superficially and on horizontal sections.
The human body is the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. Every part of the body is composed of various types of cells, the fundamental unit of life.
At maturity, the estimated average number of cells in the body is given as 37.2 trillion. This number is stated to be of partial data and to be used as a starting point for further calculations. The number given is arrived at by totalling the cell numbers of all the organs of the body and cell types. The composition of the human body is made up of a number of certain elements including carbon, calcium and phosphorus.
The study of the human body involves anatomy and physiology. The human body can show anatomical non-pathological anomalies known as variations which need to be able to be recognised. Physiology focuses on the systems and their organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis.

This pyramidal-shaped gland secretes purely serous saliva and its contribution makes up approximately thirty percent of the total saliva output.

This brief video tutorial covers the anatomy, function and innervation of the parotid gland.
Examination of parotid gland is divided into inspection & palpation. Inspection: we will look for its size, colour, any scar marks, position, position of ear lobe, whether it is obliterating the normal hollow which lies below the lobule of ear. Palpation: We will check the mobility of swelling by asking the patient to clinch his teeth so that massetter muscle contracts and we check for mobililty of parotid swelling. Superficial lobe can be easily palpated, but deep lobe palpation requires bimanual approach. One finger lies infront of tonsil, behind the 3rd molar teeth and other hand lies at back of ramus of mandible and we palpate deep lobe. To see Stensen's duct, we need to retract the cheek with the help of tongue depressor or spatula, you can palpate the end part of stensen's duct ...

Sialolithiasis (also termed salivary calculi, or salivary stones), is a condition where a calcified mass or sialolith forms within a salivary gland, usually in the duct of the submandibular gland (also termed "Wharton's duct"). Less commonly the parotid gland or rarely the sublingual gland or a minor salivary gland may develop salivary stones. The usual symptoms are pain and swelling of the affected salivary gland, both of which get worse when salivary flow is stimulated, e.g. with the sight, thought, smell or taste of food, or with hunger or chewing. This is often termed "mealtime syndrome".Inflammation or infection of the gland may develop as a result. Sialolithiasis may also develop because of the presence of existing chronic infection of the glands, dehydration (e.g. use of phenothiaz...
A video presentation of right superficial (or lateral) parotidectomy. Superficial parotidectomy involves removing all of the gland superficial to the facial nerve to treat superficial parotid tumors. While removing tumor, the critical part of the surgery is to protect and preserve all the facial nerves that are crucial to many facial functions.
The largest and thereby the most important salivary gland in the mouth is known as the Parotid gland or the glandula parotidea. The saliva produced from this gland is transported from gland though the excretory duct called the Parotid duct. This duct passes between the second upper molar teeth and reaches the cheeks. The clear saliva is even visible to the eye when the Parotid gland is gently massaged to stimulate secretion. What's more, the saliva acts as a cleansing agent with anti-bacterial properties. This saliva helps to cleanse any traces of inflammation or infections that occur in glands due to improper dental hygiene. People who have relatively lesser saliva secretion are more prone to gland inflammatory diseases as the pathogenic bacteria can reach the vulnerable glands very easil...
