2 popliteal fossa
The popliteal fossa is a diamond shaped space behind the knee with several important structures passing through it. It is bounded above and medially by the semimembranosus and semitendinosus muscles, above and laterally by the biceps femoris muscle, below and medially by the medial head of the gastrocnemius, and below and laterally by the lateral head of the gastrocnemius with the plantaris. The popliteal vessels and tibial nerve pass through the fossa, along with lymph nodes, fat, and branches of surrounding nerves. The roof of the fossa contains skin, fascia, and vessels like the short saphenous vein, while the floor is
