Groin

[2] The groin is at the front of the body on either side of the pubic tubercle, where the lower part of the abdominal wall meets the thigh.

[5] In the groin, underneath the skin, there are three to five deep inguinal lymph nodes that play a role in the immune system.

The inguinal ligament runs from the pubic tubercle to the anterior superior iliac spine, and its anatomy is very important for hernia operations.

Like other flexion surfaces of large joints (popliteal fossa, armpit, cubital fossa and essentially the anterior part of the neck), it is an area where blood vessels and nerves pass relatively superficially, and with an increased amount of lymph nodes.

In a venography procedure, the groin is the preferred site for incisions to enter a catheter into the vascular system.
