Final answer:
Joint mobility is the ability to move a joint through its normal range of motion. It is influenced by the structural classification of the joint, as well as ligaments and muscles that support it.
Step-by-step explanation:
The ability to move a joint through its normal range of motion (ROM) is referred to as joint mobility. Joint mobility is influenced by the structural classification of the joint, as well as the ligaments and muscles that support it. For example, a ba ll-and-socket joint like the shoulder allows for a wide range of motion due to the lack of ligament support, while a hin ge joint like the hip has restricted range of motion but provides stability. The range of motion of a joint can be assessed by a physical therapist to determine its functionality and create an appropriate treatment plan.
