Posterior Compartment Of Thigh Flashcards
(28 cards)
What are the boundaries of the popliteal fossa
Superolateral: biceps femoris
Superomedial: semitendinosus and semimembranosus
Inferolateral: lateral head of gastrocnemius and plantaris
Inferomedial: medial head of gastrocnemius
Where does the blood supply of the posterior compartment of thigh come from
Perforating branches of profunda femoris artery
What is the continuation of the femoral artery
Popliteal artery
What is the organization of the artery, vein, nerve from medial to lateral in the popliteal fossa
Artery (popliteal artery)
Vein (popliteal vein)
Nerve (tibial)
The small Saphenous vein is a branch off what vein
Popliteal vein
The union of what veins forms the popliteal vein
Anterior + posterior tibial veins
Popliteal lymph nodes receive lymph from where
Superficial lymph vessels (lateral leg and foot)
Deep lymph vessel ( anterior and posterior tibial vessels)
Where do the efferent vessels from the popliteal lymph nodes go?
Deep inguinal lymph nodes
What nerve is the tibial nerve a branch of
Sciatic
What are the branches of the tibial nerve in the popliteal fossa
Muscular branches
Articular branch to knee joint
Medial sural cutaneous nerve
How is the sural nerve formed
Communicating Branch from lateral sural nerve joins medial sural cutaneous nerve
Tibial nerve ascends along posterior leg with what vein
Small Saphenous
