Vasculature of the Lower Extremities Flashcards
the femoral artery goes throug the ___ ___ to supply the lower leg
adductor hiatus
which artery supplies the head of the femur?
lateral circumflex artery
the tibial and fibular arteries are branches of the ___ artery
femoral artery
how does the fascia help with the venous system
in addition to dilinated and protecting the compartments and lower extremities
- helps with venous of the limb return– contraction of the limb and fascia of each compartment helps with venous return
is the femoral vein deep or superficial
deep. it helps to conserve heat.
the great saphenous vein is located on the ___ surface of the leg. is it deep or superficial?
located on the medial-anterior surface of the lef. it is SUPERFICIAL
which component of lower leg vasculature helps with temperature egulation
the veins of the lower lef. superficial veins on surface can release heat, and deep veins can conserve heat.
the femoral triangle is bound by the ____ ligament, ___ and __ __
the femoral triangle is bound by the inguinal ligament, sartorius and adductual longus
the posterior tibial and fibular veins (both ___ layered) join the anterior tib+fib to form the ___ vein
the posterior tibial and fibular veins (both deep layered) join the anterior tib+fib to form the femoral vein
___ veins connect superficial and deep veins but valves do not allow them to flow from deep to superficial. What is the reason behing this?
the valves prevent the pressure release of the deep veins. dysfunction of these PERFORATOR veins can cause varicose veins.
LABEL THE PERFORATOR VEINGS
DBC: dodd, Boyd, cockette
note the lymphatic drainage system:
lymph nodes follow venous drainage. inguinal lymph nodes are part of the femoral triangle
the main superficial/surface and deep veins
- great saphenous (medial and anterior, small saphenous is posterior)
- femoral (DEEP-- great saphenous vein joins the femoral vein in the femoral triangle)
- external iliac (deep)
