Final answer:
Crepitation is the term used to describe the sound or feel of broken bones rubbing against each other.
Step-by-step explanation:
The sound or feel of broken bones rubbing against each other is called crepitation.
Crepitation occurs when there is movement between the broken ends of a bone, causing them to rub together. This can happen when a bone is fractured and the fragments are not in proper alignment or healing properly.
For example, if someone fractures their arm and the two ends of the bone do not align properly, they may experience crepitation when they move their arm.
