In brief: Rib-breastbone joint
Cracking a joint moves the parts of the joint, with the cracking noise coming from cartilage surfaces sliding, from movement of a little air-space from one place in the joint to another, or from some other non-traumatic event.
A person with no joint pains before or after cracking a joint is probably not damaging the joint. A doctor can evaluate pain or stiffness associated with cracking noises.
