In slide 183 and 184 of the submandibular gland, mucous secretory acini are those that stain lightly Identifying the glands. The three main glands: Parotid: Serous glands - lower viscosity, acini (lobules). Most tumours in this gland are benign. Submandibular: Serous and mucinous glands. Serous ~90% of gland. Mucinous ~10% of gland. Serous demilunes = mucinous gland with cap consisting of a serous glandular component. Demilune = crescent Submandibular gland.

Salivary glands are made up of secretory acini (acini - means a rounded secretory unit) and ducts. There are two types of secretions - serous and mucous.The acini can either be serous, mucous, or a mixture of serous and mucous.. A serous acinus secretes proteins in an isotonic watery fluid. A mucous acinuss secretes secretes mucin - lubricant. In a mixed serous-mucous acinus, the serous acinus. The submandibular glands are bilateral salivary glands located in the face. Their mixed serous and mucous secretions are important for the lubrication of food during mastication to enable effective swallowing and aid digestion

Submandibular glands. Human submandibular gland development starts from the completion of the sixth week of intrauterine life (Ellis & Auclair, 2008). Representing the second largest pair of human salivary glands, submandibular glands range in weight from 7 to 15 g and are located in the submandibular triangle behind the free insertion of the.

If you feel swelling underneath your lower jaw, it could be a swollen submandibular gland. Swollen submandibular glands are usually caused by tiny stones blocking the ducts that channel saliva into the mouth The submandibular glands produce 65% of the total saliva secreted from all salivary glands. Movement of the saliva is necessary for the removal of bacteria, pH buffering and oral health generally. The high shear rates during eating and swallowing maintain a constant flow of saliva from the ductal openings in the mouth to swallowing into the back of the throat [ 3 ]

Major salivary glands are characterized by the presence of numerous excretory units that consist of acini and a peculiar duct system. Under normal conditions, sebaceous glands are annexed to the duct system in the parotid and the submaxillary glands. The excretion of the saliva is assisted by the my The submandibular gland releases saliva through its main duct, Wharton's duct, while the parotid gland and sublingual gland utilize Stensen's duct and Bartholin's duct respectively. Salivary glands also play a crucial immunologic role as their secretions contain many immunoglobins, namely IgA, that help fight bacteria and other foreign antigens in the oropharyngeal environment Location of Submandibular Gland. The submandibular gland and the other salivary glands are essential for digestion and for maintaining a healthy mouth.Saliva contains enzymes that begin to break down food before it passes to your stomach, and it moistens food so that it slips easily down the esophagus

Note the serous and mucous elements of the submandibular (m is for mixed and mandibular) gland.Serous glandular tissue is not only found as acini but as serous demilunes, cells clasped on to the outside of mucous acini.They are able to pass their secretion through to the lumen through intercellular canaliculi Where is submandibular gland Located and what are its dimensions? Submandibular gland is a mixed type of gland (contains both mucous and serous acini) but is predominantly serous in nature.. Location: It is located in the anterior part of digastric triangle partly deep in the submandibular fossa of mandible and partly below the mandible. Size and shape: It is of the size of a walnut and weighs. The submandibular gland accounts for 80% of all salivary duct calculi (salivary stones or sialolith), possibly due to the different nature of the saliva that it produces and the tortuous travel of the submandibular duct to its ductal opening for a considerable upward distance.

All three major glands are closely associated and located in the subcutaneous tissue of the ventral neck area (Fig. 146). The submaxillary (submandibular) are the largest and easiest of the salivary glands to identify grossly Submandibular Gland. The submandibular gland is composed of both serous acini and mucous cells, and secretes saliva that contains more mucous than that of the parotid.

The submandibular glands are walnut-sized paired structures, lying beneath and in front of the angle of the jaw, wrapping around the posterior edge of the mylohyoid muscle The salivary glands are compound tubuloacinar glands; they have a number of secretory units called acini that communicate with the oral cavity through a complex series of ducts. As shown in Figure 12-2, some acini contain Serous Cells , other contain Mucous Cells , and still others contain both serous and Mucous Cells

Saliva is a fluid secreted by the salivary glands that keeps the oral cavity moist and also coats the teeth along with mucosa. The salivary gland possesses tubuloacinar units, and these are merocrine. The functional unit of the salivary glands is the terminal secretory piece called acini with a roughly spherical or tubular shape. It also consists of branched ducts for the passage of the saliva.
