submandibularkörteln

Submandibular glands, also known as submandibular salivary glands, are a pair of glands located beneath the lower jaw, near the angle of the mandible. They are part of the major salivary glands, which also include the parotid glands and the sublingual glands. The primary function of the submandibular glands is to produce saliva, which aids in digestion, lubrication, and protection of the oral cavity. Saliva produced by these glands is rich in mucins, amylase, and other enzymes that help break down carbohydrates and maintain oral health.

The submandibular glands are innervated by the facial nerve (cranial nerve VII), which also controls the muscles of facial expression. The glands are supplied by branches of the facial artery and drained by the submandibular lymph nodes. The submandibular glands are essential for maintaining oral hygiene and overall health, as they play a crucial role in the body's defense mechanisms against infections and diseases.

In cases of inflammation or infection, such as sialadenitis, the submandibular glands may become swollen and tender. This condition can be caused by bacterial infections, viral infections, or other underlying medical conditions. Treatment for sialadenitis typically involves antibiotics, pain relievers, and in some cases, surgical drainage of the affected gland. Proper oral hygiene and regular dental check-ups can help prevent infections and maintain the health of the submandibular glands.
