Blood Supply to the Hip & Thigh

The video tutorial provides a comprehensive overview of the major blood supply to the lower extremity, focusing on the branching of arteries and their supply to muscles in the hip, thigh, and lower leg. It covers the common iliac artery and its branches, the internal and external iliac arteries, and the transition to the femoral artery. The tutorial emphasizes the importance of understanding these branches for a solid framework in anatomy, while noting potential variations in different sources.

What is the primary function of the descending aorta in the context of lower extremity blood supply?

• To provide oxygen to the lungs

• To supply blood to the brain

• To divide into the common iliac arteries

• To supply blood to the upper limbs

Which artery is a branch of the anterior division of the internal iliac artery?

• Superior gluteal artery

• Popliteal artery

• Femoral artery

• Inferior gluteal artery

Which muscle is primarily supplied by the inferior gluteal artery?

• Tensor fascia lata

• Gluteus medius

• Piriformis

• Gluteus maximus

What is the significance of the obturator artery in relation to the femur?

• It anastomoses with the femoral artery

• It travels within the ligament to the head of the femur

• It supplies the anterior thigh

• It supplies the posterior thigh

Which artery continues as the femoral artery after passing under the inguinal ligament?

• Internal iliac artery

• External iliac artery

• Obturator artery

• Popliteal artery

What are the three branches of the femoral artery?

• External iliac, internal iliac, profunda femoris

• Inferior gluteal, obturator, profunda femoris

• Lateral femoral circumflex, medial femoral circumflex, profunda femoris

• Superior gluteal, obturator, popliteal

Which artery is known as the deep artery of the thigh?

• Profunda femoris artery

• Popliteal artery

• Obturator artery

• Femoral artery

What is the role of the genicular anastomosis?

• To supply blood to the upper limb

• To provide alternate blood flow during knee flexion

• To supply the head of the femur

• To anastomose with the obturator artery

Which artery supplies the posterior thigh compartment?

• Lateral femoral circumflex artery

• Femoral artery

• Profunda femoris artery

• Obturator artery

What happens to the femoral artery as it exits the adductor hiatus?

• It becomes the profunda femoris artery

• It becomes the external iliac artery

• It becomes the obturator artery

• It becomes the popliteal artery
