Blood Flow - Lower Extremities Flashcards
What are the branches of the common iliac A.?
external iliac A.; internal iliac A.
What does the external iliac A. turn into, and what structure marks this change?
becomes femoral A. when it passes deep to inguinal ligament
What are the branches of the external iliac A.?
deep circumflex iliac A.
What are the branches of the femoral A.?
profunda femoris A.; descending genicular A.
What are the branches of the profunda femoris A.?
medial circumflex of the femoral A.; lateral circumflex of the femoral A.; 1st-4th perforating AA.
What are the branches of the medial circumflex of the femoral A.?
ascending branch, transverse branch, acetabular branch
What are the branches of the lateral circumflex of the femoral A.?
ascending branch, transverse branch, descending branch
What does the femoral A. turn into, and what structure marks this change?
becomes popliteal A. once it exits the adductor canal through the adductor hiatus
What are the branches of the popliteal A.?
lateral superior genicular A., medical superior genicular A., lateral sural A., medial sural A., lateral inferior genicular A., medial inferior genicular A.
What does the popliteal A. turn into?
anterior tibial A. and posterior tibial A.
What are the branches of the anterior tibial A.?
anterior tibial recurrent A.
What does the anterior tibial A. turn into, and what structure marks this change?
becomes dorsalis pedis A. once it passes deep to the inferior extensor retinaculum
What does the dorsalis pedis A. become?
deep plantar A., arcuate A.
What are the three branches of the arcuate A.?
dorsal metatarsal AA. (x3)
What are the two branches of each dorsal metatarsal A.?
dorsal digital AA. (x2 per dorsal metatarsal A.)
What are the branches of the posterior tibial A.?
peroneal A.
What does the posterior tibial A. become?
lateral plantar A., medial plantar A.
What does the lateral plantar A. become?
plantar (deep) arterial arch
What are the branches of the plantar (deep) arterial arch?
plantar metatarsal AA. (x3)
What are the two branches of each plantar metatarsal A.?
plantar digital AA. (x2 per plantar metatarsal A.)
What are the three branches of the internal iliac A. that supply the lower extremeties?
superior gluteal A., obturator A., inferior gluteal A.
What vessels and nerves run through the adductor canal?
femoral A., femoral V., saphenous nerve, nerve to vastus medialis
At the location where the dorsalis pedis artery terminates to split into the arcuate artery and deep plantar artery, the deep plantar artery will _______.
dive between the 1st and 2nd metatarsals
What are the three major layers of arteries, from superior to deep?
tunica intima, tunica media, tunica adventitia/externa
