Cadavers? Illegal.
Skeletons? Sure, $6000.

you can just buy a real skeleton for $6k and it's legal in 47 states.

What 3 states don't allow it

@Stuxnet Georgia, New York, Tennessee

i used to study physiotherapy and my best friend for the 1½ year we had anatomy was my skeleton.
was a bit creepy to have a box of human bones standing around at first, but you get used to it.
sometimes i would get the skull up and place it on the box and just talk to it.
i didn't get out much back then...

Probably because a decomposing dead body is a significant biohazard, while a well-preserved skeleton doesn't do much other than sitting around (and waking up from its slumber on Halloween and attempting to conquer the world).

Are these new skeletons, or ones grandfathered in?

I want to make some kind of "right to bare arms" joke here...

@Parzi It's ironic that Tennessee doesn't allow it, yet the University of Tennessee has a plethora of skeletons in an old dorm building where they are/were being studied lol

I believe this is quite common in medical school. Ideally each student/small group would have one and they usually keep it throughout their course.

A real skeleton would have very fine features where the muscles are attached, etc, which are difficult to find in replicas.
