Week 9 - Lesson 1 (Part 1) Flashcards
What are the 3 arteries on the lower extremity peripheral tree?
- Aortoiliac
- Femoropopliteal
- Tibioperoneal
What are the aorta/iliac artery branches? (4)
- Aorta
- Common iliac
- External iliac
- lateral - Internal iliac
- medial
What does the abdominal aorta bifurcate into?
Left and right iliac vessels
Where does the abdominal aorta bifurcate at?
The umbilicus
Where do common iliac arteries transverse to?
The pelvis
- extends laterally towards the inguinal canal
Where does the internal iliac artery extend?
Medially
- supplies the pelvic organs
What artery is distal to the internal iliac artery?
The external iliac artery
What do the branches below the EIA supply?
The lower extremities
What is the order to arteries in the lower extremities? (8)
- External iliac artery
- Common femoral artery
- in the groin crease - Femoral artery
- superficial - Deep femoral artery
- profunda - Popliteal artery
- Anterior tibial artery
- lateral - Peroneal artery
- in between then anterior and posterior tibial artery - Posterior tibial artery
- medial
Hunters canal
Is an aponeurotic tunnel in the middle third of the thigh, extending from the apex of the femoral triangle to the opening in the adductor magnus, the adductor hiatus
- distal part of the thigh
What is another word for the hunters canal?
Adductor canal
What is the artery after it passes through the inguinal canal?
Common femoral artery
What does the common femoral artery bifurcate into? (2)
- Femoral artery
- superficial - Deep femoral artery
- profunda
What is just proximal to the bifurcation of the common femoral artery?
The lateral circumflex artery branches
What occasionally happens to the femoral artery?
It divides into 2 trunks (duplication) reuniting distally in the adductor canal
- AKA the Hunter’s canal
Where does the DFA bifurcate to?
Laterally
- deeply
What does the DFA supply?
Thigh muscles with many branches
What does the DFA connect?
EIA and the popliteal artery
What happens at the Hunters canal?
The Femoral Artery becomes the popliteal artery passing obliquely behind the knee in the popliteal fossa
Where does the popliteal artery trifurcate?
Below the popliteal fossa
- becomes the tibioperoneal trunk
What does the tibioperoneal trunk trifurcate into? (3)
- Peroneal artery
- posterior tibial artery
- Anterior tibial artery
What does the anterior tibial artery become?
The dorsalis pedis artery at the ankle level which supplies the foot
Where does the posterior tibial artery terminate?
At heel level
What does the posterior tibial artery become?
The plantar arteries in the foot
