Blood Supply to the Knee & Lower Leg

The video tutorial covers the blood supply to the muscles of the gluteal region, hip, and thigh, starting from the descending aorta to the femoral artery, which transitions into the popliteal artery. It explains the genicular anastomosis, a network of vessels that ensures blood flow during knee flexion. The tutorial also details the arterial branches in the lower leg, including the anterior, posterior, and fibular arteries, and their respective compartments. Finally, it touches on the blood supply to the foot, highlighting the transition of the anterior tibial artery to the dorsalis pedis artery and the posterior tibial artery to the plantar arteries.

What is the starting point of the blood supply to the gluteal region?

• Femoral artery

• Descending aorta

• Internal iliac artery

• Popliteal artery

Through which structure does the femoral artery become the popliteal artery?

• Popliteal fossa

• Adductor canal

• Genicular anastomosis

• Adductor hiatus

What is the primary function of the genicular anastomosis?

• To supply blood to the foot

• To provide an alternate blood flow during knee flexion

• To supply blood to the thigh muscles

• To connect the femoral and popliteal arteries

Which artery does the popliteal artery become as it descends through the knee?

• Anterior tibial artery

• Posterior tibial artery

• Femoral artery

• Fibular artery

Which artery supplies the anterior compartment of the lower leg?

• Posterior tibial artery

• Fibular artery

• Anterior tibial artery

• Popliteal artery

What nerve is associated with the anterior compartment of the lower leg?

• Tibial nerve

• Deep fibular nerve

• Sural nerve

• Superficial fibular nerve

Which artery supplies the lateral compartment of the lower leg?

• Anterior tibial artery

• Posterior tibial artery

• Fibular artery

• Popliteal artery

What is the role of the fibular artery in the lower leg?

• Directly supplies the lateral compartment

• Supplies the anterior compartment

• Terminates in the foot

• Provides alternate blood flow to other arteries

Which artery becomes the dorsalis pedis artery at the ankle?

• Fibular artery

• Posterior tibial artery

• Popliteal artery

• Anterior tibial artery

What are the two arteries into which the posterior tibial artery divides at the foot?

• Superior and inferior genicular arteries

• Dorsalis pedis and fibular arteries

• Anterior and posterior tibial arteries

• Medial and lateral plantar arteries
