Question

What artery provides blood flow to a gastrocnemius flap?

1) Femoral artery
2) Popliteal artery
3) Superficial femoral artery
4) Popliteal vein

Answer 1

The popliteal artery is responsible for providing blood flow to the gastrocnemius flap, stemming from the continuation of the femoral artery.

Step-by-step explanation:

The popliteal artery provides blood flow to the gastrocnemius flap. This artery is a continuation of the femoral artery, which becomes the popliteal artery as it passes posterior to the knee. The popliteal artery then branches into the anterior and posterior tibial arteries, with the posterior branch assisting in supplying blood to the lower limbs, including the gastrocnemius muscle.
