Sublingual Gland

Sublingual Gland: functions and features

The Sublingual Gland is a paired salivary gland that is located on the upper surface of the diaphragm of the mouth on both sides of the tongue. These glands are the smallest salivary glands, but despite this, they play an important role in the digestion process and oral health.

Each sublingual gland has a main duct called the major sublingual duct. It opens with one common opening with the duct of the submandibular gland. In addition, the gland has several small ducts, most of which open in the oral cavity directly on the sublingual fold of the mucous membrane.

The main function of the sublingual glands is the production of saliva, which plays an important role in the digestion process. Saliva contains various enzymes that help break down food in the mouth and begin the process of digestion. In addition, saliva moisturizes the oral cavity and protects teeth and gums from bacteria and other harmful substances.

In addition to the function of producing saliva, the sublingual glands are also involved in the process of speech and swallowing. They help hold food in the mouth and mix it with saliva, forming a bolus for further digestion. In addition, the sublingual glands help in amplifying the sound when pronouncing certain sounds.

Even though the sublingual glands are the smallest salivary glands, they have their own unique structure and function in the human body. In addition, their health is important for the proper functioning of the entire body, so it is recommended to see a dentist for regular check-ups and treatment of possible diseases.
