Q

External iliac artery changes to femoral artery when it passes through these boundaries:

  1. Passes inferior to
  2. Passes medial to
  3. Passes superior to

~what does this create

A
  1. Inguinal ligament
  2. Iliopectineal arch
  3. Iliopubic ramus

Q

Two branches of femoral artery and what they supply

A
  1. Deep branch - posterior compartment
  2. Circumflex branches - proximal femur~ these are branches of deep branch: lateral goes around front of femoral neck; medial goes behind and then they anastomose with each other
