Which vessels drain the soleal and gastrocnemius plexus?

The popliteal vein is the correct vessel that drains the soleal and gastrocnemius plexus. These plexuses are located in the posterior compartment of the leg and are important for venous drainage from the deep structures in that area, specifically the muscles of the calf.

The soleal and gastrocnemius muscles are responsible for various functions, including plantar flexion of the foot and aiding in venous return through the calf muscle pump mechanism. Venous blood from these muscles is collected into the soleal and gastrocnemius veins, which then course into the popliteal vein located in the popliteal fossa behind the knee. This anatomical arrangement is essential for effective blood return to the heart.

In contrast, the other vessels listed have different functions or regions of drainage. The femoral vein primarily receives blood from the superficial structures of the thigh and abdominal walls. The anterior tibial vein drains blood from the anterior compartment of the leg, which is distinct from the posterior compartments draining into the popliteal vein. The great saphenous vein is a superficial vein that drains blood from the skin and subcutaneous tissue of the lower limb but does not collect venous blood from the deep calf muscles effectively. Thus, the pop
