Shoulder+The+Basics

The shoulder's purpose is to attach the arm to the torso while also being a __diathroses joint__. It does this by using it's three bones: the __humerus__, the __clavicle__, and the __scapula__. These bones join together and make joints which not only let the arm move around, but also manipulate objects around them by lifting, pulling, and pushing.
