Artery Of Thigh Flashcards
What is the main artery of the lower limb?
Femoral artery
The femoral artery is crucial for supplying blood to the lower limb.
The femoral artery is a continuation of which artery?
External iliac artery
The external iliac artery is the terminal branch of the abdominal aorta.
When does the external iliac artery become the femoral artery?
When it crosses under the inguinal ligament
This transition occurs as the artery enters the femoral triangle.
Where does the profunda femoris artery arise from?
Postero-lateral aspect of the femoral artery
The profunda femoris artery is a significant branch supplying deeper structures of the thigh.
Fill in the blank: The femoral artery enters the _______ triangle.
Femoral
The femoral triangle is an important anatomical region in the upper thigh.
What is the main function of the femoral artery?
It supplies blood to the thigh and lower limb tissues.
The femoral artery is a major blood vessel in the thigh, crucial for delivering oxygenated blood.
Name the three main branches of the profunda femoris artery.
- Perforating branches
- Lateral femoral circumflex artery
- Medial femoral circumflex artery
These branches are essential for supplying muscles in the thigh.
What do the perforating branches of the femoral artery supply?
They supply the adductor magnus and contribute to the supply of muscles in the medial and posterior thigh.
The perforating branches consist of three or four arteries.
What area does the lateral femoral circumflex artery supply?
It supplies some of the muscles on the lateral side of the thigh.
This artery wraps around the anterior, lateral side of the femur.
What does the medial femoral circumflex artery supply?
It supplies the neck and head of the femur.
This artery wraps around the posterior side of the femur.
True or False: A fracture of the femoral neck can damage the medial femoral circumflex artery.
True
Damage to this artery can lead to avascular necrosis of the femur head.
Fill in the blank: Avascular necrosis of the femur head can occur due to damage to the _______.
[medial femoral circumflex artery]
This condition is a serious complication following a fracture in the femoral neck.
What is the pathway of the femoral artery after exiting the femoral triangle?
It continues down the anterior surface of the thigh via the adductor canal
The adductor canal is a tunnel that allows the femoral artery to descend while supplying blood to the anterior thigh muscles.
What muscles does the femoral artery supply during its descent?
The anterior thigh muscles
The femoral artery provides necessary blood flow to these muscles, which are crucial for movement.
What is the adductor canal?
A tunnel that the femoral artery travels through in the thigh
It connects the femoral triangle to the adductor hiatus.
What is the adductor hiatus?
An opening in the adductor magnus
It is where the femoral artery transitions to the popliteal artery.
What happens to the femoral artery at the adductor hiatus?
It enters the posterior compartment of the thigh and becomes the popliteal artery
This transition occurs proximal to the knee.
Fill in the blank: The femoral artery becomes the _______ after passing through the adductor hiatus.
popliteal artery
What artery arises from the internal iliac artery and supplies the medial thigh?
Obturator artery
The obturator artery descends via the obturator canal to enter the medial thigh.
What are the two branches of the obturator artery?
- Anterior branch
- Posterior branch
The anterior branch supplies the pectineus, obturator externus, adductor muscles, and gracilis, while the posterior branch supplies some deep gluteal muscles.
What muscles does the anterior branch of the obturator artery supply?
- Pectineus
- Obturator externus
- Adductor muscles
- Gracilis
These muscles are located in the medial thigh region.
What does the posterior branch of the obturator artery supply?
Some deep gluteal muscles
The posterior branch primarily targets specific deep muscles in the gluteal region.
Which arteries supply the gluteal region?
- Superior gluteal artery
- Inferior gluteal artery
These arteries arise from the internal iliac artery and enter the gluteal region via the greater sciatic foramen.
True or False: The femoral artery is the only artery supplying the lower limb.
False
Other vessels, including the obturator and gluteal arteries, also supply the lower limb.
