What Bone is this?

This is the right anterior femur. There are a few ways to say it, but I’m going to call it the right anterior femur for this answer. The femur itself (whether left or right) is often considered the longest and strongest bone in the body.

It is the bone found in your upper leg, and according to multiple sources, is the only bone in that area of the body - which means this picture is of the right anterior and the right posterior femur. Either way, this is the right femur.

The femur extends from the hip bone to the patella, or knee cap. It takes the brunt of a lot of movements in terms of where a movement starts. Every movement with the upper leg starts there.
