Nerve and Blood supply of Lower Limb Flashcards
In the thigh what movements of the hip are produced by the muscles of the medial compartment?
Adduction
What significant transition occurs at the inguinal ligament?
External Iliac artery -> Femoral artery
Where would you palpate for the femoral artery?
At the femoral triangle just inferior to the inguinal ligament, midway between the ASIS and pubis symphasis
What structures make up the borders of the femoral triangle and what travels through the triangle?
Lateral - Sartorius
Medial - Adductor longus
Superior - Inguinal ligament
Femoral sheath containing nerve/artery/vein (lateral to medial)
