The Supratrochlear Lymph Nodes are a group of lymph nodes located above the medial epicondyle of the humerus, near the elbow joint. They are part of the lymphatic system, which plays a crucial role in the body's immune response.

Anatomy

The Supratrochlear Lymph Nodes are small, bean-shaped structures that are part of the lymphatic system. They are located above the medial epicondyle of the humerus, near the elbow joint. These nodes are responsible for draining lymph from the medial side of the hand, the little finger, and the medial side of the forearm.

Function

The primary function of the Supratrochlear Lymph Nodes, like other lymph nodes, is to filter lymph. Lymph is a clear fluid that circulates throughout the lymphatic system, carrying cells that help fight infections and diseases. The Supratrochlear Lymph Nodes filter lymph that comes from the areas of the body they drain, helping to remove harmful substances and prevent them from spreading.

Clinical Significance

Enlargement or inflammation of the Supratrochlear Lymph Nodes, known as lymphadenopathy, can be a sign of infection or disease in the areas of the body they drain. This can include infections of the hand or forearm, or systemic conditions such as lymphoma or metastatic cancer.
