limb vasculature Flashcards
what are the 3 branches of the arch of the aorta
branchiocephalic
left common carotid
left subclavian
what 2 branches come of the brachiocephalic artery
right common carotid
right subclavian
at what point does the subclavian artery become the axillary artery
past the inferior border of the 1st rib
at what point does the axillary artery become the brachial artery
at the inferior border of theres major muscle
where can you feel the brachial artery pulse
at the elbow, medial to the biceps tendon
what does the brachial artery bifurcate into (2 things)
radial and ulnar arteries
to what point do the radial and ulnar artery reach the hand
radial artery reaches posterior to the thumb
ulnar artery reachs lateral to the pisiform bone
what do the radial and ulnar artery link as
superficial and deep palmer arch
describe the structure/ points of the palmer arch on the hand
from the radial artery that reaches posterior to the thumb, it goes along the palmer of the hand then runs posterior again to the 5th metacarpal
deep veins of the arms have same location and name as artery priorly mentioned
what are the 2 main superficial veins of the arms
cephalic and bascilic
describe the position of the cephalic superficial vein
start on the lateral aspect of the dorsal venous arch and go up to the anterior lateral epicondyle
describe the position of the basilic superficial vein
start on the medial aspect of dorsal venous arch and go up to the anterior aspect of the medial epicondyle
how does the cephalic vein join to the axillary vein
continue laterally from the lateral epicondylitis dyle to the midpoint of the humerus
then begin to arch the cephalic vein medially to finish inferior ally to the coracoid process (just under the clavicle)
how does the basilic vein join to the axillary vein
continue the basilica vein from the medial epicondyle up to the axilla (armpit) and from there it connects to the axillary vein
which major vessel does the left and right brachiocephalic vein join to form
superior vena cave
where are the humeral and cubital/supratroclear nodes locate
humeral = medial side of arm close to armpit
cubital = medial side of arm just above the medial epicondyle
what does the aortic branch spilt into as it first reaches the lower limbs
common iliac arteries
what do the common iliac arteries split into
internal iliac arteries and external iliac arteries
at what point does the external iliac artery become the femoral arteries
once it passes the inguinal ligament
how does the superficial femoral artery descend from the external iliac artery
it depends posterior-medially towards the back of the knee
at what point does the superficial femoral artery become the popliteal artery?
when it passes through the adductor hiatus, which is a hole in the adductor Magnus muscle
how does the popliteal artery decend
down through the centre of the posterior aspect of the knee down to the bulk of the gastrocnemius (calf)
what 2 things does the popliteal artery spilt into
anterior and posterior tibial arteries
what 2 bones does the anterior tibial artery pass anteriorly of
tibia and fibula
what artery does the anterior tibial artery descend into and how
continue down the centre of the tibia, past the ankle joint and towards the large toe
where does the posterior tibial artery descend down to
the medial malleolus
what are the superficial veins of the lower limb
great saphenous vein and lesser saphenous vein
describe the branching of the greater saphenous vein
starting from the superficial venous arch on the foot
continue the medial branch of the venous arch passing anterior to the medial malleolus
continue along the medial aspect of leg up to the inferior of knee then it continues posterior-medially until superior of knee
and all the way to the common femoral artery
what deep vein does the great saphenous join to
common femoral vein
where are the lymph nodes of the lower limb
right above the crease of the knee / popliteal fossa
