The inguinal region is the groin i.e. the area where the front of the thigh meets the anterior abdominal wall. There is an oblique, slightly curved groove at this point which marks the position of the inguinal ligament, the strong, fibrous rolled-up lower border of the external oblique (the outermost of the abdominal wall muscles) which is attached to the pubic tubercle near the mid-line of the body and to the anterior superior iliac spine at the lower margin of the waist. The groin is the region in which the femoral nerve and vessels enter the thigh behind the inguinal ligament. |
