Click the structure names below to identify the following muscles and neurovasculature structures of the posterior thigh compartment and leg region.
At the same time, on the opposite limb, use the dissect and/or highlight tool to locate the same structure to verify that you understand the positional relationships of the anatomical structure on the virtual cadaver.
