Vascular Space
The vascular lacuna (Latin: ''lacuna vasorum'') is the compartment beneath the inguinal ligament which allows for passage of the femoral vessels, lymph vessels and lymph nodes. Its boundaries are the iliopectineal arch, the inguinal ligament, the lacunar ligament, and the superior border of the pubis. The structures found in the vascular lacuna, from medial to lateral, are: * Cloquet's node; * Femoral vein; * Femoral artery; and * Femoral branch of the genitofemoral nerve The vascular lacuna is separated from the muscular lacuna The muscular lacuna (Latin: ''lacuna musculorum'') is the lateral compartment of the thigh inferior to the inguinal ligament, for the passage of the iliopsoas muscle, the femoral nerve and the lateral cutaneous nerve of the thigh The lateral ... by the iliopectineal arch. The lacunar ligament can be a site of entrapment for femoral hernias.Ross, L.M., Lamperti, E.D. (2006). Thieme: Atlas of Anatomy: 489 References Muscular system ...

Inguinal Ligament
The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: *Psoas major, iliacus, pectineus *Femoral nerve, artery, and vein *Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint of the ingui ...
