Anatomy of Leg Circulation Flashcards
(27 cards)
What is the arterial supply to the upper limb (arm - hand)?
Subclavian artery (under clavicle)
- –> Axillary artery
- –> Brachial artery and Deep Brachial artery
- –> Radial and ulnar artery
- –> Superficial and deep palmar arches
- –> Metacarpal and digital arteries (4 per digit)
What is the arterial supply to the lower limb (groin to foot?
External iliac artery
—> Femoral and Deep femoral artery
—> Popliteal artery
POPLITEAL FOSSA
—> Posterior tibial artery —> Plantar arteries
Anterior tibial artery —> Dorsalis pedis —> Arcuate
artery
—> Metatarsal and digital arteries (4 per digit)
What are end arteries? Why are they important?
Only blood supply to given area (no collaterals)
Untreated occlusion —> infarction
What is the main pulse point in the neck?
Bifurcation of common carotid
Anterior to SCMD at level of thyroid cartilage
What are the main pulse points in the UL?
Brachial (cubital fossa)
Radial (Lateral to flexor carpi radialis)
What are the main pulse points in the LL?
Femoral (inferior to midpoint of inguinal ligament) Popliteal (popliteal fossa) Posterior tibial (posterior border of medial malleolus) Dorsalis pedis (lateral to extensor halllucis longus)
List the deep fascia in the UL
Pectoral
Deltoid
Brachial
Antebrachial fascia
List the deep fascia in the LL
Fascia lata (thigh) Iliotibial tract Grural fascia (leg)
What is the venous drainage of the UL (hand to arm)?
Superficial and deep palmar venous arches
—> Dorsal venous network
—> DEEP: Radial and ulnar veins
—> SUPERFICIAL: Cephalic (lateral), M
Median cubital vein
Basillic (medial) –> Brachial vein
—> Axillary vein
—> Subclavian vein at lateral border of rib 1

What is the venous drainage of the LL (foot to groin)?
Dorsal venous arch —> Great saphenous vein (medial) –>
Femoral vein
–> Small saphenous vein (P midline) –>
Popliteal vein –> Femoral vein
Plantar arch —> Posterior and anterior tibial veins
Fibular vein —> Popliteal vein –>
Femoral vein
Deep Femoral vein and Femoral vein —> External Iliac vein
—> Common iliac vein
What are the superficial veins of the lower limb?
Great saphenous vein
Small saphenous vein
What is the function of perforating veins?
Connect superficial and deep veins
What happens when venous valves are incompetent? What helps to push blood back to the heart?
Blood pools in the superficial veins = varicose veins
Musculovenous pump
Where is the most common site for venous ulceration?
Gaiter area - medial aspect of distal leg
What are the lymph nodes of the upper limb?
Cubital, lateral pectoral, apical pectoral nodes
Where does lymph drain from the basillic vein?
Cubital —> Lateral axillary nodes
Where does lymph drain from the cephalic vein?
Apical axillary nodes
Where does lymph drain from the deep veins of the upper limb?
Lateral axillary nodes
What do lymph nodes follow?
Follow veins
What are the lymph nodes of the lower limb?
Superficial and deep inguinal, popliteal lymph nodes
Where does lymph drain from the great saphenous vein?
Superficial inguinal —> Deep inguinal —? External iliac
