Metacarpal or Metatarsal?

I have been thinking a lot about bones lately.. I guess I think a lot about bones all the time, but lately I have been trying to consider them more completely, in relation to one another, and to better be able to identify which bones are which, where they come from on the body, and which bodies the particular bones I find make up? There are so many questions that come wrapped in bone that it’s kind of fun to take the time to consider some of them.
