Final answer:
The common peroneal nerve is not located in the popliteal fossa, unlike the popliteal artery, popliteal vein, and tibial nerve, which are typically found in this anatomical region.
Step-by-step explanation:
The structure that is not present in the popliteal fossa is C) Common Peroneal Nerve. The popliteal fossa typically contains the popliteal artery, popliteal vein, and tibial nerve. The common peroneal nerve, however, branches from the sciatic nerve and courses around the fibular neck, which is not located within the popliteal fossa.
The popliteal artery is a continuation of the femoral artery that, as it passes behind the knee, gives rise to the anterior and posterior tibial arteries. The posterior tibial artery supplies blood to the posterior tibial region and is itself a branch of the popliteal artery. The popliteal vein forms from the union of the anterior and posterior tibial veins, draining blood from the lower leg to re-circulate through the body.
