I would like to know how my forearm bones move inside my forearm when I'm twisting my hand. (Also, it would help to see the hand bones action too). "twisting hand" means to me the motion in which the rest of the body is in place except the hand which turns from upside up to downside.
I have the intuition that the bones inside my forearm move between themselves to make my hand twist, but am not sure if that is true.
I would like pictures of the forearm bones before and after twisting. Animations would also be great of course.
