Arteries Flashcards
The external iliac artery continues as…?
The femoral artery
When does the external iliac artery become the femoral artery?
When it passes under the inguinal ligament
What does the femoral artery enter at the beginning of the thigh?
Femoral triangle
What does the femoral artery do in the femoral triangle?
Gives off branch
the profunda femoris artery
Where does the profunda femoris artery travel?
Posteriorly
Distally
What are the branches of the profunda femoris artery?
Perforating branches
Lateral femoral circumflex artery
Medial femoral circumflex artery
What do the perforating branches do?
Perforate adductor magnus
Where does the lateral femoral circumflex artery travel?
Anteriorly around femur
Where does the medial femoral circumflex artery travel?
Posteriorly around femur
What does the medial femoral circumflex artery supply?
Head and neck of femur
After the femoral artery leaves the femoral triangle, where does it travel?
Down the adductor canal
What is the continuation of the femoral artery?
Popliteal artery
When does the femoral artery become the popliteal artery?
After it passes through the adductor hiatis opening
The internal iliac artery gives rise to…?
Obturator artery
What does the obturator artery descend into?
The medial thigh
What does the obturator do in the medial thigh?
Divide into branches
What do the branches of the obturator artery do?
Supply medial thigh muscles
What else does the internal iliac artery give rise to apart from the obturator artery?
Superior gluteal artery
Inferior gluteal artery
How do the gluteal arteries enter the gluteal region?
Through greater sciatic foramen
Superior - above piriformis
Inferior - below piriformis
What do the gluteal arteries supply?
Gluteal region muscles
What does the popliteal artery do in the knee joint?
Gives off genicular branches
What do genicular branches supply?
Knee joint
Where does the popliteal artery travel?
Down the popliteal fossa
Where does the popliteal artery end?
Lower border of popliteus
Where does the posterior tibial artery travel?
Down posterior leg
along surface of deep muscles
How does the popliteal artery end?
Divides into anterior and posterior tibial arteries
What does the posterior tibial artery accompany?
Tibial nerve
What does the posterior tibial artery do in the leg?
Gives off fibular artery
How does the posterior tibial artery enter the foot?
Through the tarsal tunnel
What does the posterior tibial artery do in the foot?
Divides into medial plantar artery
Lateral plantar artery
What do the medial and lateral plantar arteries do?
Form part of the deep plantar arch
Where does the fibular artery travel?
Laterally
then down the lateral leg
What does the fibular artery supply?
Lateral leg muscles
Where does the anterior tibial artery travel?
Passes through gap in interosseus membrane
enters anterior leg
travels down anterior leg
What does the anterior tibial artery become in the foot?
Dorsalis pedis artery
Where does the dorsalis pedis artery travel in the foot?
Inferiorly towards sole of foot
What does the dorsalis pedis artery anastamose with?
Lateral plantar artery
What is formed between the dorsalis pedis artery and the lateral plantar artery?
Deep plantar arch
What does the dorsalis pedis artery supply?
Dorsum of foot
What do the medial and lateral planter arteries supply?
Plantar surface of foot
What does the deep plantar arch supply?
Toes
