superficial inguinal node, a node in one of the two groups of inguinal lymph glands in the upper femoral triangle of the thigh. The nodes form a chain distal to the inguinal ligament and receive afferent vessels from the skin of the penis, scrotum, perineum, buttocks, and abdominal wall below the level of the umbilicus. Compare anterior tibial node, popliteal node.
