I guess technically correct, because they're mostly latin loan words.

I didn’t know that terminology, thank you.

But reading the article, are those not applicable only to body parts? Would an astronaut ever say to another astronaut, while floating in different orientations, “Hit the button to your superior”?

Either way, I think it’s at least correct to say that there are no layman words for it.
