Femoral hernia to insinuate in the femoral ring, a consequence of which is development of a femoral peritoneal sac. Femoral hernia A hernia is caused by the protrusion of a viscus (in the case of groin hernias, an intra-abdominal organ) through a weakness in the abdominal wall. This weakness may be inherent, as in the case of inguinal, femoral and umbilical hernias. On the other hand, the weakness may be caused by previous surgical incision through the muscles and fascia in the area; this is termed an incisional hernia. Femoral hernias occur just below the inguinal ligament, when abdominal contents pass through
Inguinal lymph nodes Inguinal lymph nodes Inguinal lymph nodes are the lymph nodes in the inguinal region (groin). They are located in the femoral triangle, and are grouped into superficial lymph nodes, and deep lymph nodes. The superficial lymph nodes have three divisions – the superomedial, superolateral, and inferior superficial lymph nodes. They are divided into three groups: There are approximately ten superficial lymph nodes, and they drain to the deep inguinal lymph nodes. Inguinal lymph nodes may normally be up to 2 cm in size. They receive lymphatic afferents from the following: There can be three, four or five deep inguinal lymph
