Description
The supratrochlear lymph nodes are comprised of one to two nodes located superior to the medial epicondyle of the humerus and medial to the basilic vein. These nodes form part of the cubital lymph nodes, nodes which are scattered within the cubital fossa, near the bifurcation of the brachial artery.
The supratrochlear lymph nodes drain lymph from the third to fifth fingers, and the medial portions of the forearm. The efferent vessels of the nodes accompany the basilic vein in the arm.

Lymph Node
Lymph nodes are a part of the lymphatic system, which also includes lymphatic vessels that collect interstitial fluid or lymph (including invaded microbes in case of infections) from all vascularized tissues and discharge it into their draining lymph nodes.
