Salivary Gland : Detailed Explanation


What Is Salivary Gland?

Salivary glands are small organs in the mouth that produce saliva. Saliva is a fluid that helps to wash food down and lubricate our teeth.

Saliva is a fluid that is produced in the salivary glands. It is composed of proteins, salts, and water.

Salivary glands are one of the most important and commonly used organs. They secrete saliva which is a type of fluid. Saliva helps to neutralize the acidity of the stomach and the environment around the mouth.

Salivary glands produce saliva, a fluid that helps to digest food. They are located in the upper jaw just below the teeth.

The three major salivary glands

The three major salivary glands are: the parotid, the submandibular, and the sublingual. They are located below the lower jawbone and produce saliva.

Saliva is the fluid that is produced in response to the stimulation of the three major salivary glands. The three major salivary glands are the parotid gland, the submandibular gland, and the sublingual gland. Saliva is constantly being secreted and it helps to clean and lubricate our teeth, gums, and lips.

You have 3 major pairs of salivary glands, inclusive of your:

  • Sublingual glands: These are underneath both aspects of your tongue, below the ground of your mouth.

  • Submandibular glands: Located underneath your jaw, your submandibular salivary glands encompass  components: the superficial lobe and the deep lobe. Like your sublingual glands, the saliva produced for your submandibular glands input your mouth from beneath your tongue.

  • Parotid glands: Your parotid glands are just in front of your ears. Similar to your submandibular glands, your parotid glands have  elements: superficial and deep. The saliva produced via your parotid glands enters your mouth from small ducts near your top molars.

Salivary Gland function

The saliva is a viscous fluid that is produced by the salivary glands. The salivary glands are located in the neck region of the head. The salivary glands are responsible for secreting the saliva. Saliva is a fluid that is used for communication and for breaking down food.

The saliva is continuously secreted from the salivary glands to moisten and lubricate the oral cavity. The saliva also contains enzymes that help with the digestion of food.

Example, saliva:

  • Keep your mouth and throat lubricated and secure.

  • Moistens meals so it’s less difficult to swallow.

  • Contains an enzyme referred to as amylase, which helps your belly destroy down starches in meals.

  • Keep your mouth smooth.

  • Helps lessen your chance of cavities and gum ailment.

  • Helps hold the pH balance on your mouth.

Salivary gland problems

Salivary gland problems can occur when salivary glands do not make enough saliva, or when the saliva made is of poor quality. Many disorders can cause problems with saliva production including Sjögren’s syndrome, diabetes, HIV/AIDS, and certain cancers. Common symptoms of salivary gland disorders include a dry mouth, trouble swallowing, and mouth pain. Salivary gland disorders are usually treated by stimulating saliva production or by managing the symptoms.

Many specific troubles can intervene with the function of the salivary glands or block the ducts so they can't drain saliva. The following are some of the more commonplace salivary gland problems:

  1. Salivary stones, or sialoliths. The maximum common motive of swollen salivary glands, salivary stones are buildups of crystallized saliva deposits. Sometimes salivary stones can block the drift of saliva. When saliva cannot go out through the ducts, it backs up into the gland, causing pain and swelling. Pain is usually off and on, is felt in one gland, and gets step by step worse. Unless the blockage is cleared, the gland is in all likelihood to come to be inflamed.

  2. Salivary gland infection, or sialadenitis. Bacterial infection of the salivary gland, most commonly the parotid gland, may additionally result while the duct into the mouth is blocked. Sialadenitis creates a painful lump in the gland, and foul-tasting pus drains into the mouth.

  3. Sialadenitis is greater common in older adults with salivary stones, but it can additionally appear in toddlers for the duration of the primary few weeks after start. If not handled, salivary gland infections can cause intense ache, high fevers, and abscess (pus series).

  4. Infections. Viral infections which include mumps, flu, and others can cause swelling of the salivary glands. Swelling happens in parotid glands on both facets of the face, giving the arrival of "chipmunk cheeks."

  5. Salivary gland swelling is commonly associated with mumps, going on in approximately 30% to forty% of mumps infections. It usually starts about 48 hours after the start of other symptoms including fever and headache.

  6. Other viral illnesses that cause salivary gland swelling include the Epstein-Barr virus (EBV), cytomegalovirus (CMV), Coxsackievirus, and the human immunodeficiency virus (HIV).

  7. Bacterial infections normally motivate one-sided salivary gland swelling. Other signs consisting of fever and ache will accompany the swelling. The bacteria are usually the ones observed inside the mouth, as well as staph micro organisms. These infections most usually affect the parotid gland. Dehydration and malnutrition raise the risk of having a bacterial infection.

  8. Cysts. Cysts can broaden within the salivary glands if accidents, infections, tumors, or salivary stones block the glide of saliva.Some babies are born with cysts inside the parotid gland because of a hassle with the improvement of the ears. It can appear as a blister or smooth, raised region. Cysts might also intervene with eating and talking.

  9. Tumors. Several exceptional types of tumors can affect the salivary glands. They can be cancerous (malignant) or noncancerous (benign). The  most common tumors are pleomorphic adenomas and Warthin's tumor.

  10. Pleomorphic adenomas most generally affect the parotid glands, however also can have an effect on the submandibular gland and minor salivary glands. The tumor is generally painless and grows slowly. Pleomorphic adenomas are benign (noncancerous) and are more common in ladies than guys.

  11. Warthin's tumor is likewise benign and influences the parotid gland. Warthin's tumor can develop on each side of the face and affects more men than girls.

  12. While maximum salivary gland tumors are benign, a few may be cancerous. Malignant tumors include mucoepidermoid carcinoma, adenoid cystic carcinoma, adenocarcinoma, low-grade polymorphous adenocarcinoma, and malignant combined tumor.

  13. Sjögren's syndrome. This is a chronic autoimmune sickness in which cells of someone's immune system assault the salivary and other moisture-producing glands, main to dry mouth and eyes.About half of of people with Sjögren's syndrome also have growth of the salivary glands on each facets of the mouth, which is normally painless.

Health of the salivary glands

Over six hundred and fifty salivary glands are located in and around the mouth, with most concentrated in the mucous membranes that line the floor of the mouth. Saliva is produced in these glands, which are responsible for keeping the mouth moist and lubricated and for aiding in the digestion of food. Without saliva, speaking and eating would be difficult, and the mouth would be susceptible to infection. The salivary glands can be classified according to their position in the mouth, their structure, or the type of saliva they produce.

Saliva is produced in the mouth by the salivary glands. A normal person produces about 1 to 2 liters of saliva each day. Saliva serves many important functions in the mouth, such as keeping the mouth moist, which makes it easier to swallow. It also helps to protect teeth from decay by washing away food and bacteria, and it aids in the digestion of food.

While you can’t usually save you salivary gland problems, there are things you could do to reduce your chance. For instance:

  • Drink masses of water.

  • Quit smoking.

  • Limit your consumption of alcohol.

  • Tell your healthcare company if medications are making your mouth dry.

  • Practice correct oral hygiene.
