Superficial inguinal lymph nodes drain from all of the following except:

Superficial Inguinal Lymph NodesThe horizontal groupThe medial members of the group receive superficial lymph vessels from the anterior abdominal wall below the level of the umbilicus and from the perineum. The lymph vessels from the urethra, the external genitalia of both sexes (but not the testes), and the lower half of the anal canal are drained by this route.The lateral members of the group receive superficial lymph vessels from the back below the level of the iliac crests.The veical group lies along the terminal pa of the great saphenous vein and receives most of the superficial lymph vessels of the lower limb.The efferent lymph vessels from the superficial inguinal nodes pass through the saphenous opening in the deep fascia and join the deep inguinal nodes.Deep Inguinal Lymph NodesThe deep nodes are located beneath the deep fascia and lie along the medial side of the femoral vein; the efferent vessels from these nodes enter the abdomen by passing through the femoral canal to lymph nodes along the external iliac aery Lymphatic Drainage of the PenisFrom most of the penis, lymph drains into the superficial inguinal lymph nodes.Vessels from the glans penis drain into the deep inguinal lymph nodes.
