8. Femoral sheath
 Funnel shaped
 Extra-peritoneal fascia derived from fascia
transversalis in front and the psoas fascia
behind
 Covers femoral vessels an inch below the
inguinal lig.
 Femoral N lie laterally & outside the sheath
 Medialmost compartment femoral canal
 femoral br. genitofemoral N pierces its lat. wall
 Great saphenous V pierces its medial wall

Femoral ring & hernia
Boundaries
Anteriorly – medial part of the inguinal
ligament
Medially – crescentic edge of the lacunar
ligament
Posteriorly – pectineal ligament &
