Parotid Anatomy

Key facts about the parotid gland; Gross anatomy: Largest of the salivary glands Paired organ Irregular in shape, but roughly pyramidal Divided into superficial and deep lobes: Anatomical relations: The facial nerve (CN VII), external carotid artery, retromandibular vein all pierce the parotid gland Drains via the parotid duct of Stense Anatomy . The parotid glands develop early—at just six to seven weeks into gestation. Starting as tiny buds in the oral cavity, these glands eventually form two lobes that sit just in front of the ears on either side, stretching from the cheekbone down to the jawline. Blood is supplied to the parotid gland by the external carotid artery.  The parotid gland is a bilateral structure, which displays a lobular and irregular morphology. Anatomically, it can be divided into deep and superficial lobes, which are separated by the facial nerve. It lies within a deep hollow, known as the parotid region. The parotid region is bounded as follows: Superiorly - Zygomatic arch The parotid glands are located in front and beneath the ear. A duct, called Stensen's duct, drains saliva from the parotid gland into the mouth, at the area of the upper cheeks. The submandibular glands are found on both sides, just under and deep to the jaw, towards the back of the mouth

Surface Anatomy of the Parotid Duct. On the face the parotid duct is represented by the middle third of the line going from lower border of tragus to the midpoint between the ala of the nose and the red margin of the upper lip. The accessory gland is emptied by a small duct that opens into the upper aspect of the parotid duct. Clinical Significanc Parotid salivary gland anatomy. The parotid salivary gland is the largest salivary gland. It weighs around 20-30 grams (0.71- 1.06 oz) and helps form the cheeks by giving fullness. It has an inverted pyramidal shape, and it produces around 60-65% of total saliva

The salivary glands, while often overlooked, are a key part of our digestive system. There are three main pairs of salivary glands: the parotid, submandibular, and sublingual glands. There are also a few smaller companions called accessory salivary glands, which are sprinkled over the palate, lips, cheeks, tonsils, and tongue The salivary glands are an important set of exocrine glands that functions to produce, modify and secrete saliva into the oral cavity. They glands are divided into two main types: the major paired salivary glands, which includes the parotid, submandibular and sublingual glands, and the minor salivary glands, which line the mucosa of the upper aerodigestive tract and the overwhelming entirety. An accessory parotid gland lies adjacent to Stensen's duct and is distinctly separated from the main body of the parotid gland. 3,5,10,11 The average distance of separation between the main parotid gland and the accessory parotid gland is 6.0 mm. 11 Parotid tissue that lies anterior to the main duct with no distinct separation from the main gland is considered to be an anterior facial process. The sublingual gland is the smallest of the three major salivary glands [1], which also include the parotid and submandibular glands. The sublingual gland lies between the muscles of the floor of the oral cavity, which include the geniohyoid muscle, hyoglossus muscle medially, and the mylohyoid muscle inferiorly. The mandible borders the sublingual glands laterally [2]

Anatomy. The salivary glands in dogs and cats are categorized as major or minor, depending on their size and location and the contribution of saliva. The four major salivary glands in dogs and cats are the parotid, mandibular, sublingual, and zygomatic 16 (Figure 88-1) In this article, we present the anatomy of the major salivary glands and neighboring structures as seen at US, as well as the US features of the most common pathologic conditions affecting the parotid and submandibular glands. These conditions include inflammatory diseases, sialolithiasis, sialosis, Sjögren syndrome,. The saliva that's secreted by the parotid gland passes into the parotid duct, which emerges from the anterior border of the gland, and passes forward around the anterior border of the masseter. The parotid duct enters the oral cavity by passing through the buccinator muscle and through the underlying mucous membrane, at about the level of the second upper molar tooth BACKGROUND AND PURPOSE: Masses in the parotid tail can be a source of consternation to radiologists and clinicians; inaccurate localization may lead to significant iatrogenic complication. We sought to review the pertinent anatomic localizing features of the parotid tail, relevant facial nerve anatomy, and sources of clinical and radiologic confusion Cystic parotid lesions.

Parotid Glands. The parotid glands are the largest salivary glands. They are located just in front of the ears. The saliva produced in these glands is secreted into the mouth from a duct near your upper second molar. Each parotid gland has two parts, or lobes: the superficial lobe and the deep lobe. Between the two lobes is the facial nerve Salivary gland anatomy. The three pairs of major salivary glands in humans are the parotid (PG), submandibular (SMG), and sublingual (SLG) glands. The anatomical architecture of all three glands is essentially the same: an arborized ductal structure that opens into the oral cavity with secretory endpieces, the acini, producing saliva A parotid abscess may put pressure on facial nerves. One common condition involving the parotid glands is parotitis, an inflammation of the glands.This inflammation can be caused by a number of things, including mumps, a childhood disease which used to be quite common.When the parotid glands become inflamed, they swell up, causing facial pain and a distinct distortion of the face around the jaw Parotid Gland Infection Symptoms. If your parotid gland duct is obstructed long enough, it can become infected and lead to other symptoms besides swelling, such as: Tender, painful lump in your cheek. Foul-tasting discharge from the duct into your mouth. Fever, chills, and fatigue. Difficulty fully opening your mouth, speaking, chewing, or.

Download the brochure in pdf format for more information The salivary glands are exocrine glands that are positioned in the head, in and around the oral cavity and secrete their salivary contents into the mouth. Their function is to help keep the oral mucosa protected and lubricated. They also help in the initial stages of digestion during mastication of food, so that a food bolus is created and ready to be swallowed for further processing Salivary glands are classified as exocrine, and as such, they produce secretions (i.e., saliva) onto an epithelial surface via a system of ducts. Saliva secretion and production are mediated by the autonomic nervous system (ANS) and thus; salivary glands have both parasympathetic and sympathetic innervation INTRODUCTION: THE ANATOMY AND PHYSIOLOGY OF SALIVARY GLANDS benefits of saliva is that it is easily available for non-invasive collection and analysis.

Abstract Tubarial glands or tubarial salivary glands are recently reported as a pair of macroscopic salivary glands in the nasopharynx The parotid gland is an indispensable part not only of our digestive system, but also of our immune system. Anatomy and function of the parotid gland In the case of man there is that Parotid gland on both sides of the face. It covers roughly the back of the lower jaw bone and is therefore in front of and under the ear Description. The parotid gland, the largest of the three, varies in weight from 14 to 28 gm. It lies upon the side of the face, immediately below and in front of the external ear. The main portion of the gland is superficial, somewhat flattened and quadrilateral in form, and is placed between the ramus of the mandible in front and the mastoid process and Sternocleidomastoideus behind.

Structure. The parotid duct is formed when several interlobular ducts—the largest ducts inside the parotid gland—join. It emerges from the gland and runs forward along the lateral side of the masseter muscle.In this course, the duct is surrounded by the buccal fat pad. It takes a steep turn at the border of the masseter and passes through the buccinator muscle, opening into the vestibule. The salivary glands. Let's take a closer look at some of the major salivary glands: The parotid glands are the largest of the salivary glands. They are located superficially in the lateral aspect of the face, anterior and inferior to the ear. Each parotid gland is made up of lobules of glandular tissue and weigh approx. 25g Anatomy. There are two parotid glands in the human body. Each parotid gland is located high in the neck just below the ears. A salivary duct by which saliva is secreted (produced and released), runs through the inside of each cheek from each gland. Furthermore, the extratemporal (outside temporal bone) facial nerve and its subsidiaries run through the parotid gland and innervate (supply nerves. The salivary glands are composed of two types of secretory cells, serous and mucous. Serous cells produce a watery secretion containing ions, enzymes, and a small amount of mucin. Mucous cells produce mucus. The submandibular and parotid glands contain a large percentage of serous cells. The sublingual glands contain mostly mucous cells
