The knee and popliteal fossa Flashcards
Superolateral border of the popliteal fossa, superficially
Biceps femoris
Superomedial border of the popliteal fossa, superficially
Semimembranosus
Inferiolateral and inferomedial border of the popliteal fossa, superficially
Lateral and medial heads of the gastrocnemius
Posterior border of the popliteal fossa, superficially
Skin and popliteal fascia
Contents of the popliteal fossa
Small saphenous vein, Popliteal arteries and veins, Tibial and common fibular nerves, Posterior cutaneous nerve of the thigh, Popliteal lymph nodes and lymphatic vessels
The popliteal fascia is continuous superiorly with which fascia and inferiorly with which fascia?
Superiorly: fascia lata
Inferiorly: crural fascia
All important neurovascular structures that pass from the thigh to the leg do so by traversing the popliteal fossa. T/F
T
The arrangement of the vessels and nerves within the popliteal fossa, superficial to deep
Nerves - veins - arteries
While in the popliteal fossa, the popliteal artery divides into these branches to supply the capsule and ligaments of the knee joint
Superior medial genicular artery, Superior lateral genicular artery, Middle genicular artery, Inferior lateral genicular artery, Inferior medial genicular artery
The common fibular is the medial branch of the sciatic nerve. T/F
F
It is the lateral branch.
The medial sural cutaneous nerve is derived from which nerve in the popliteal fossa?
Tibial nerve
Importance of the genicular anastamosis
Maintains blood supply to the leg during full knee flexion when the popliteal artery may be kinked.
Which nerve winds around the neck of the fibula to divide into its terminal branches?
Common fibular nerve
When does the femoral artery become the popliteal artery?
When it passes through the adductor hiatus
The descending genicular artery is a branch of which artery?
Femoral artery
