also you show me how to the FEA for this too
well you use a saw bones template for the structure
You serious? You want someone to show how to model BONES? And also you want someone to show how to do structural analysis to those BONES?
Ok let's start from the source, in which format you have the bone models? Do you have a scanned point cloud or something similar? Because there's no point in modeling a bone from scratch because it won't ever be similar to the real thing. And also bone density is not constant from what I know, so you need a custom material for that.
