fed by anterior tibial artery at ankle; feeds middle of dorsal foot. palpatable for a pulse.
|
|
deep veins of lower limb
|
drain the lower limb and return the blood back to the heart. named according to accompanying arteries
|
|
superficial veins of the lower limb
|
greater and lesser saphenous veins
|
|
greater saphenous vein
|
runs up the medial leg and thigh to join the femoral nerve, which then runs deep to send the blood back to the heart!
|
|
lesser saphenous vein
|
joins the popliteal vein in the middle of the posterior leg
|
|
peroneal artery
|
a lateral branch of the posterior tibial artery, this branches into the medial and lateral plantar arteries.
|
|
the arteries of lower limb begin when:
|
the external iliac artery crosses the inguinal ligament and becomes the femoral artery in the femoral triangle
|
|
anterior tibial artery
|
branch of popliteal artery. passes between fibula/tibia to anterior leg. at ankle becomes dorsalis pedis
|
|
posterior tibial artery
|
branch from popliteal artery. feeds posterior muscles of leg, we focus on the lateral branch, the peroneal artery.
|
|
Lumen
|
the hole, open part of vessel
|
|
tunic intima
|
internal layer of the blood vessel; composed of endothelial cells with an elastic membrane
|
|
tunica media
|
middle layer of the lining of the blood vessel; composed of smooth muscle, elastic tissue, and concentrically organized
|
|
tunica externa (adventitia)
|
external, outermost layer of the blood vessel; composed of white, fibrous connective tissue
|
|
arteries
