The Popliteal Fossa EXPLAINED | Boundaries & Contents

The video tutorial provides an in-depth look at the popliteal fossa, a space located at the posterior aspect of the knee. It covers the boundaries formed by various muscles, including the biceps femoris and gastrocnemius. The tutorial also details the contents of the fossa, such as the tibial and common peroneal nerves, and the popliteal artery and vein. Additionally, it explains the transition of the femoral artery and vein into the popliteal vessels and discusses the origins of the sural nerve.

Which muscle forms the superior lateral boundary of the popliteal fossa?

• Semitendinosus

• Plantaris

• Biceps femoris

• Gastrocnemius medial head

What is the primary function of the popliteal fossa?

• To provide structural support to the knee

• To allow passage of vessels and nerves from the thigh to the leg

• To act as a shock absorber during movement

• To store synovial fluid

At what point does the sciatic nerve bifurcate into the tibial and common peroneal nerves?

• At the knee joint

• Inferior angle of the popliteal fossa

• Superior angle of the popliteal fossa

• Within the adductor canal

What happens to the femoral artery as it enters the popliteal fossa?

• It splits into the anterior and posterior tibial arteries

• It becomes the popliteal artery

• It forms the sural nerve

• It merges with the femoral vein

Which of the following is NOT a content of the popliteal fossa?

• Popliteal vein

• Tibial nerve

• Femoral artery

• Common peroneal nerve

What is the role of the sural nerve?

• To control knee joint movement

• To relay sensory information from the posterior leg and lateral foot

• To supply blood to the foot

• To provide motor function to the leg

Where does the popliteal artery branch into the anterior and posterior tibial arteries?

• Within the adductor canal

• At the knee joint

• At the inferior angle of the popliteal fossa

• At the superior angle of the popliteal fossa
