What is Structure which lies outside the femoral sheath and explain in detail?
Femoral nerve Femoral sheath Femoral sheath is a funnel shaped fascial prolongation around proximal pa of femoral vessels, situated in the femoral triangle, below the inguinal ligament. It is 3-4 cm long. It is formed by fascia iliaca. Femoral sheath is divided into 3 separate fascial compaements by septa :? i) Lateral compament :- It contains femoral aery and femoral branch of genitofemoral nerve. ii) Intermediate compament :- Femoral vein. iii) Medial compament (femoral canal) :- It is conical in shape, wider above adn narrow below. The wider upper opening is known as femoral ring, which is potentially a weak point in lower abdomen and is the site for femoral hernia. Femoral ring is bounded : Anteriorly by inguinal ligament, medially by lacunar ligament, posteriorly by pectineus with its covering fascia, and laterally by septum separating it from femoral vein. Femoral canal contains lymph node of cloquet or Rosenmuller and lymphatics.
