Which of the following is an anatomical factor that limits range of motion (ROM)?

The structure of the joint itself is a key anatomical factor that limits range of motion (ROM). Each joint in the human body has a specific design that dictates how far it can move. For instance, ball-and-socket joints like the shoulder allow for a greater range of motion compared to hinge joints like the knee. The shape of the bones involved, the type of cartilage present, and the ligaments that support the joint all contribute to the overall mobility or limitations experienced in that area.

When considering the anatomical makeup, factors such as the depth of a socket, the size of the bones, and the presence and condition of connective tissues directly influence how well a joint can function within its range of motion. Thus, understanding these structural characteristics is crucial for assessing and addressing limitations in flexibility and movement.
