Submaxillary

Submaxillary (also known as the submandibular gland) is one of the three major salivary glands in humans. It is located in the submandibular triangle of the neck, beneath the floor of the mouth. The submaxillary gland produces a mixture of both serous fluid and mucus, and contributes to around 70% of the total salivary volume.

Anatomy

The submaxillary gland is a mixed gland with a predominantly serous secretion. It is smaller and more irregular in form than the parotid gland. It is shaped somewhat like a flattened ellipse, and its size and weight vary. On an average, it might be as long as 6 cm and weighs about 10 grams.

Function

The submaxillary glands, like the other salivary glands, secrete saliva, which begins the process of digestion. The saliva also cleanses the mouth and moistens the food, making it easier to swallow.

Clinical significance

Diseases of the submaxillary gland, though less common than those of the parotid gland, are still occasionally seen in clinical practice. These can include infections, stones (sialolithiasis), and tumors.
