- sublingual glands secrete a saliva that is predominantly mucous in character.

What are the 3 salivary glands and their ducts?
The three major salivary glands are the parotid, submandibular, and sublingual glands. Stensen’s duct drains the parotid gland opposite the upper second molar. Wharton’s duct drains the submandibular and some of the sublingual glands into the floor of the mouth near the frenulum of the tongue.
What are the 6 salivary glands and its location?
Besides the many minute glands that secrete saliva, there are three major pairs of salivary glands: the parotid, the submandibular, and the sublingual glands. The parotid glands, the largest of the pairs, are located at the side of the face, below and in front of each ear.

What does it mean when your salivary glands are swollen?
Infections. Viral infections such as mumps, flu, and others can cause swelling of the salivary glands. Swelling happens in parotid glands on both sides of the face, giving the appearance of “chipmunk cheeks.” Salivary gland swelling is commonly associated with mumps, happening in about 30% to 40% of mumps infections.
What causes an infected salivary gland?
Salivary Infection: Causes
The most common causes of acute salivary gland infections are bacteria, especially Staphylococcus aureus, or staph. Viruses and fungi can also cause infection in the glands. (Mumps is an example of a viral infection of the parotid glands.)

Where do salivary glands drain?
Saliva drains into the mouth through small tubes called ducts. The parotid gland makes 25 percent of the saliva and drains into the mouth near the upper teeth. The submandibular gland makes 70 percent of the saliva and drains into the mouth from under the tongue.
Where are the 3 salivary glands located?
There are three pairs of large salivary glands. Parotid glands are found in front of and just below each ear. Submandibular glands are below the jaw. Sublingual glands are under the tongue.
What is submandibular duct?
The submandibular duct (also known as Wharton’s duct) allows the passage of saliva from the submandibular gland to the sublingual papilla located anteriorly.
Where does saliva come from in your mouth?
The glands that make saliva are called salivary glands. The salivary glands sit inside each cheek, at the bottom of your mouth, and near your front teeth by the jaw bone. There are six major salivary glands and hundreds of minor ones. Saliva moves through tubes called salivary ducts.
Can you live without salivary glands?
Sublingual glands are located under the tongue and the submandibular glands are beneath the jaw. Without these crucial salivary glands, the mouth would not be able to maintain tooth health nor moisture of any kind.
What are symptoms of salivary gland problems?

Is salivary gland surgery painful?
A saliva duct is a tube that carries saliva from the gland into the mouth. The area below your jaw may be sore for several days after your surgery. The area also may be slightly swollen or bruised. It will probably take 1 to 2 weeks for the cut (incision) to heal.
