Suprahyoid lymph nodes

Suprahyoid lymph nodes are a group of lymph nodes located above the hyoid bone in the human body. They are part of the lymphatic system, which plays a crucial role in the body's immune response.

Anatomy

The suprahyoid lymph nodes are situated above the hyoid bone, near the submandibular gland. They receive lymphatic drainage from the tissues above the hyoid bone, including parts of the tongue, the floor of the mouth, and the skin and mucous membrane of the lower part of the face.

Function

The primary function of the suprahyoid lymph nodes, like other lymph nodes in the body, is to filter lymph. Lymph is a clear fluid that circulates throughout the lymphatic system, carrying cells that help fight infections and diseases. The suprahyoid lymph nodes filter the lymph that drains from the areas above the hyoid bone, removing harmful substances and producing lymphocytes, a type of white blood cell that fights infections.

Clinical significance

The suprahyoid lymph nodes can become enlarged or inflamed in response to infection or disease in the areas they drain. This condition is known as lymphadenopathy. In some cases, suprahyoid lymphadenopathy can be a sign of serious conditions such as cancer or tuberculosis. Therefore, any persistent swelling of the suprahyoid lymph nodes should be evaluated by a healthcare professional.
