Anatomy of Venous Circulation Flashcards
What does the brachial artery bifurcate into?
Radial and ulnar arteries
Which of the radial and ulnar arteries is the most superficial?
ulnar
why is there a deep brachial artery as well as a brachial?
flexing elbow cuts off blood supply to brachial so need an alternative
what is an end artery?
only blood supply to a given area of the body; no collaterals present
what would happen if an end artery was occluded?
infarction
name the arteries of the arm from proximal to distal
subclavian axillary brachial/deep brachial radial/ulnar superficial/deep palmar arches metacarpal digital
name the arteries of the leg from proximal to distal
external iliac femoral/deep femoral popliteal ant/post tibeal dorsalis pedis
what does the deep femoral artery supply?
hamstrings and back of leg
what do superficial veins drain into?
deep veins
what tissue do superficial veins run in?
superficial fascia
what tissue do deep veins run in?
deep to deep fascia or in body cavities
name the superficial veins of the upper limb and where they arise from
cephalic vein and basilic vein
dorsal venous network
which is the most medial of the superficial veins of the upper limb?
basilic vein
what does the cephalic vein drain into
axillary vein
what does the basilic vein drain into
brachial vein
at what anatomical landmark does the axillary vein become the subclavian vein?
lateral border of rib 1
name the superficial veins of the lower limb
great saphenous
small saphenous
dorsal venous arch
where do the great and small saphenous veins arise from?
dorsal venous arch
which is the more medial of the great and small saphenous veins?
great saphenous
what vein does the great saphenous vein drain into?
femoral vein
what vein does the small saphenous vein drain into?
popliteal
name the deep veins of the lower limb from distal to proximal
plantar arch post/ant tibial fibular popliteal femoral/deep femoral
what are perforating veins?
connect superficial veins to deep veins by perforating the deep fascia; ensure unidirectional blood flow
how does the clinical presentation of venous insufficiency in the superficial and deep veins differ?
superficial= ULCER deep= THROMBOSIS
most common site of venous ulceration?
medial aspect of the distal leg
where do the deep lymphatics of the upper limb drain into?
lateral axillary lymph nodes
name the superficial lymphatics that follow the basilic vein route
cubital lymph nodes
name the superficial lymphatics that follow the great saphenous vein route
superficial inguinal lymph nodes => deep inguinal nodes
name the superficial lymphatics that follow the small saphenous vein route
popliteal nodes=> deep inguinal nodes => external iliac nodes
where do the external iliac lymph nodes drain into?
common iliac nodes => lumbar lymphatics
