The popliteal fossa is the main conduit for neurovascular structures entering and leaving the leg.
Contents of popliteal fossa (medial to lateral):
Popliteal artery
Popliteal vein
Tibial nerve
Common fibular nerve (common peroneal nerve)
The most superficial of the contents of the popliteal fossa…
The tibial and common fibular nerves
The tibial and common fibular nerves are branches of…

In the popliteal fossa, the common fibular nerve follows…
The biceps femoris tendon, travelling along the lateral margin of the popliteal fossa.
Which vein drains into the popliteal vein?
The small saphenous vein pierces the popliteal fascia and passes between the two heads of gastrocnemius to empty into the popliteal vein.
In the popliteal fossa, the deepest structure is…
