Labial glands

Labial glands are a type of exocrine gland located in the human mouth. They are found in the lips and are responsible for the production of saliva, which aids in the process of digestion and keeps the mouth moist.

Etymology

The term "labial" is derived from the Latin word "labium", which means "lip". The term "gland" comes from the Latin word "glandula", meaning a small acorn, due to the shape of some glands.

Structure

Labial glands are a type of minor salivary gland. They are located in the mucous membrane of the lips and are most numerous near the opening of the mouth. Each gland is a small, round, yellowish body, about the size of a small pin-head.

Function

The primary function of the labial glands is to produce saliva. Saliva produced by these glands contains mucin, a protein that helps to lubricate the mouth and aid in the process of digestion. Saliva also helps to keep the mouth clean by washing away food particles and bacteria.
