Etymology
Joint comes from a form of the joining verb meaning “joined” or “connected.” It names the meeting place that holds bones together, extended to connections between other parts.
In context
we call that the angle of the rib. Where these bones interact, we have joints. And between the tubercle of the rib and the transverse process, we have the costotransverse joint.
