Where are the salivary glands?

Saliva is a secretion produced by the salivary glands in the human mouth. Saliva also contains DNA tissue, and saliva testing can also be used to detect whether there is a relationship. Although everyone has a large amount of saliva in their mouth, normal people do not know where the salivary glands that secrete saliva are located in the human mouth. The following article explains the specific distribution location of salivary glands.

The salivary glands are located around the mouth and secrete saliva in the mouth. They are divided into large and small types.

The minor salivary glands are located in the facial masks throughout the mouth. They are mucous glands and do not have dedicated ducts. Saliva is secreted directly from the cells into the mouth.

There are three pairs of major salivary glands:

1. Parotid gland: The parotid duct papilla opens on the buccal mucosa opposite the crown of the maxillary second molar. That is the piece of flesh that protrudes on the edge of the second upper molar.

2. Submandibular gland: opens at the sublingual caruncle. That is the back of the tongue.

3. Sublingual gland: opens on the mucosal surface of the sublingual fold. That is, the folds at the root of the tongue under the tongue.

Common salivary gland diseases include the following:

① Salivary gland stones. The most common submandibular duct stones. Main symptoms: pain when eating and swelling of the submandibular gland. Ductal stones may be palpable. X-rays may show positive stones. Treatment: Surgical removal of the stone.

② Sialadenitis. It is mainly caused by salivary gland stones and infections such as pyogenic bacteria, viruses, and tuberculosis. Clinical manifestations: redness, swelling, pain in the salivary glands, and fever throughout the body. In cases of purulent disease, the salivary duct opening is red and pus can be squeezed out; in cases of viral disease, the saliva at the duct opening is clear; in cases of sialolymphadenitis, the duct opening is normal. Treatment: Antibacterial and anti-inflammatory.

③ Miguel's disease, Sjögren's syndrome (dry mouth syndrome). Autoimmune diseases of the salivary glands. Lymphocytes infiltrate and replace the alveoli. Clinical manifestations: dry mouth, dry eyes, swollen salivary glands, joint disease, etc. Sialography, isotope scanning, and biopsy pathological examination are of diagnostic value. There is no cure yet, but Chinese and Western medicine can be used for symptomatic treatment to improve saliva secretion.

④ Benign hypertrophy of salivary glands. Compensatory or degenerative lesions of the salivary glands. The reactions of malnutrition, hepatitis, diabetes, etc. in the salivary glands. Clinical manifestations: soft swelling of salivary glands, without discomfort. Sialogram showed benign hypertrophy. No treatment is usually required.
