Question 5

Above the umbilicus the lymphatic drainage goes to the
anterior or axillary nodes.

Below the umbilicus the lymphatic drainage goes to the

This pattern is followed on the posterior abdominal wall too.

green = genitofemoral L1,2
yellow = lat cutanueos L2,3
red = obturator L2,3,4
orange =femoral L2-4
