inclines to the midline of the fibula and penetrates the deep fascia

ascends between the heads of gastroc

empties into popliteal vein in popliteal fossa

what are perforating veins?

veins that connect the deep and superficial veins. blood can only flow from superficial to deep because of valves.

origin, course and distribution of superior gluteal artery

O posterior division of internal iliac artery

C leaves pelvis through greater sciatic foramen, superior to piriformis

D gluteal muscles and tensor fascia latae

origin course and distribution of inferior gluteal artery

O anterior division of internal iliac artery

C leaves pelvis through greater sciatic foramen inferior to piriformis

D piriformis, coccygeus, levator ani, and gluteal muscles

origin and course of external iliac artery

O common iliac artery

C follows the iliopsoas muscle. becomes the femoral artery at the inguinal ligament. gives rise to inferior epigastric a and deep iliac circumflex a.

course of femoral vein

continuation of popliteal vein proximal to adductor hiatus

fed by profunda femoris vein and great saphenous vein

becomes the external iliac vein after passing posterior to inguinal ligament

in adductor canal, lies posterlaterally and posterior to the femoral artery

origin and course of femoral artery

continuation of external iliac artery distal to inguinal ligament

lateral to femoral vein in femoral triangle

descends on borders of iliopsoas and pectineus

enters adductor canal deep to sartorius

exits adductor canal passing through addcutor hiatus and becomes popliteal artery

origin and course of deep femoral artery

arises from femoral artery in femoral triangle. in middle third of thigh is separated from femoral artery by adductor longus. gives off three or four perforating arteries that wrap around posterior femur and feed adductor magnus, hamstring, and vastus lateralis muscles

origin and course of lateral circumflex femoral artery

can arise from deep femoral artery or femoral artery. encircles the thigh and anastosomes with the medial circumflex artery and supplies lateral thigh muscles and proximal femur.

origin and course of medial circumflex femoral artery

most likely arises from deep femoral artery but may arise from femoral artery

supplies most of blood to head and neck of femur. it's branches are posterior retinacular arteries.

passes deep between iliopsoas and pectineus to reach posterior aspect of femoral neck where it runs deep to quadratus femoris

course and distribution of perforating arteries

come from deep femoral artery

wrap around posterior aspect of femur

feed hamstrings, adductor magnus and vastus lateralis

popliteal vein course

continuation of posterior tibial veins

superficial to and in the same fibrous sheath as popliteal artery throughout course

popliteal v becomes femoral vein in adductor hiatus

small saphenous enters popliteal vein in popliteal fossa

popliteal artery course and distribution

continuation of femoral artery

begins where femoral artery passes adductor hiatus

passes through popliteal fossa

ends by dividing into anterior and posterior tibial arteries
