T
5 it lies in front of the popliteal artery
F
Concerning the popliteal vein:
The popliteal vein is formed by the confluence of the anterior
tibial and posterior tibial veins. The most superficial structures in
the popliteal fossa are the two branches of the sciatic nerve (tibial
nerve and common peroneal nerve)
The popliteal artery lies in front of the popliteal vein.

knee joint

Concerning the popliteal vein and its tributaries:
The popliteal vein is formed by the confluence of the anterior
tibial vein and posterior tibial vein. It receives the genicular veins

20. 1 The muscle which forms the upper lateral boundary of the fossa is inserted onto the
fibular head

medial meniscus

F
Concerning the muscular boundaries of the popliteal fossa:
Biceps femoris which forms the upper lateral boundary of the popliteal fossa is inserted onto the head of fibula.
The medial head of gastrocnemius forms the lower medial boundary of the fossa and does indeed contribute to
the tendo calcaneus.
The lower lateral boundary of the fossa is formed by the lateral head of gastrocnemius and plantaris. Both
muscles are innervated by the tibial nerve, not common peroneal nerve.
The upper medial boundary of the popliteal fossa is formed by the semitendinosus and semimembranosus,
neither of which is attached to the medial meniscus. Both muscles are innervated by the tibial nerve not femoral
nerve.
