o Iliopsoas muscle
o Femoral Nerve
o N. Cutaneus Femoris Lateralis
- Lacuna Vasorum
o Femoral Artery
o Femoral Vein
o Genitofemoral nerve
o Lymph node
Femoral Canal:
- Does not exist under normal conditions, only during pathological cases like hernia
- Lacuna Vasorum is covered by Peritoneum, deep ingunal lymph nodes and the medial femoral intermuscular septum
- The other opening, hiatus saphenous is covered by fascia cribrosa
Femoral Triangle
- Borders:
- 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
- Superior medial margin: M. semitendinosus and semimembranosus
- Superior lateral margin: Femoral Biceps
- Inferior medial margin: Medial head of Gastrocnemious muscle
- Inferior Lateral margin: Lateral head of the Gastrocnemious muscle
Canal of the lower region of the leg.
- Borders: M. soleus, m. hallucis longus and tibialis posterior and flexus hallucis longus
