- Obturator Membrane
- Obturator Canal
Muscular Space and The Vascular Space:
- Ingunal Ligament (Ligamentum Inguinale)
- Lacunar Ligament (Ligamentum Lacunare)
- Pectineal Ligament (Ligamentum Pectineale)

- Base: M. iliopsoas and m. pectineus
- Superior: Inguinal ligament
- Medial: Adductor longus
- Lateral: Musculus sartorius
Adductor Canal
- Femoral vein and artery inside it
- Bordered by Vastus medialis, sarotrius and assuctor longus
Popliteal fossa
