ANATOMY - limb circulation Flashcards
when does the subclavian artery change into the axillary artery
lateral to the first rib
what branches off of the brachial artery
deep brachial artery
where does the brachial artery bifurcate
cubital fossa (anterior part to elbow)
what does the brachial artery bifurcate into
radial and ulnar arteries
what does the radial artery go into
where does this supply
deep palmar arch
dorsum of hand
what does the ulnar artery go into
where does this supply
superficial palmar arch
palm of hand
how many metacarpal and digital arteries are there in each hand
20 - 4 for each digit
where does the external iliac artery turn into the femoral artery
under inguinal ligament
where do the medial and lateral circumflex femoral arteries that supply the hip come from
deep femoral artery
what is the other blood supply to the hip (not the medial and lateral circumflex femoral arteries)
ligamentum teres
what do the medial and lateral circumflex femoral arteries give off
retinacular arteries
do the perforator arteries come off the deep femoral artery at the same place as the medial and lateral circumflex arteries
no
they come off lower down and supply the shaft of the femur
where does the femoral artery change to the popliteal artery
adductor hiatus
what does the popliteal artery bifurcate into
posterior and anterior tibial arteries
what does the posterior tibial artery bifurcate into
where
medial and lateral plantar arteries
between medial malleolus and Achilles tendon
what branches off the posterior tibial artery
fibular artery
what does the anterior tibial artery change into
dorsalis pedis artery
what does the dorsalis pedis artery change into
arcuate artery
what happens to the lateral and medial plantar arteries
anastomose (join together again) to form the deep plantar arch
what is between the deep plantar arch (from medial and lateral plantar arteries) and the arcuate artery (from dorsalis pedis)
metatarsal arteries
how many digital arteries are there in the foot
20 (4 for each digit)
what are the 4 pulse points in the lower limb
femoral
popliteal
posterior tibial
dorsalis pedis
what shouldnt you give near end arteries (digits)
adrenaline anaesthetics
what happens to superficial veins
they drain into deep veins
what is the branch of the ulnar artery called
posterior interosseous branch
