The supratrochlear lymph nodes are superficial lymph nodes found in the supratrochlear region around the humerus.
The supratrochlear lymph nodes are small and few in number. One or two nodes are found proximal to the medial epicondyle of the humerus, medial to the basilic vein.
Note that vessels from these areas are in free connection with vessels from the rest of the fingers, hand and forearm.
Efferents from the supratrochlear lymph nodes accompany the basilic vein in the upper arm, to join the deeper lymph vessels.
