69
Femoral and Obturator Nerve Origins
L2-L4
70
Femoral Nerve enters thigh by
Under inguinal ligament
71
After passing under the inguinal ligament, the femoral nerve
Instantly splits into branches to the anterior thigh muscles, anterior cutaneous nerve of thigh and saphenous nerve
72
Saphenous nerve supplies
Cutaneous medial leg and foot
73
Obturator nerve enters thigh through
Obturator foramen
74
Obturator Nerve supplies…
Med thigh muscles and cutaneous
75
Femoral nerve supplies
Ant thigh muscles, ant thigh cut (via ant cut nerve thigh) medial leg and foot (via saphenous)
76
Superifical Veins Lower Limb
Small Saphenous = post leg Great Saphenous = med leg
77
Femoral Triangle Order from Lat->Med

84
Femoral Canal allows for
Expansion of Femoral Vein
85
Adductor Canal is
Pathway for femoral vessels from femoral triangle to popliteal fossa
86
Adductor Canal anaesthesia used for
