The Popliteal Fossa | Boundaries & Contents

The video tutorial provides an in-depth look at the popliteal fossa, a diamond-shaped area on the posterior aspect of the knee. It covers the boundaries formed by muscles such as the hamstrings and gastrocnemius, the roof and floor structures, and the significance of this anatomical space. The tutorial also details the contents, including the popliteal artery and vein, and discusses potential injuries related to the popliteal artery. Additionally, it explains the nerves present in the fossa, including the sciatic, tibial, and sural nerves.
