Flashcards in Nerve and Blood supply of Lower Limb Deck (17):
1

In the thigh what movements of the hip are produced by the muscles of the medial compartment?

Adduction

2

What significant transition occurs at the inguinal ligament?

External Iliac artery -> Femoral artery

3

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

4

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)

5

Where is the adductor hiatus found and what significant transition occurs within it?

Found in Adductor magnus
Femoral artery becomes popliteal artery
