Which movement describes rotation around a joint outwards away from the midline of the body?

The movement that describes rotation around a joint outwards away from the midline of the body is known as external rotation. This action occurs when a limb or part of the body turns away from the center line. For instance, in the context of the shoulder joint, when the arm is raised and rotated outward, that is considered external rotation. This movement is essential in various athletic activities and helps improve mobility and flexibility in the joints.

In contrast, elevation refers to the upward movement of a body segment, internal rotation is the turning motion towards the midline, and circumduction describes a circular movement where one end of a limb remains stationary while the other moves in a circular path. Understanding these movement patterns is vital for comprehending functional movements in exercise and rehabilitation.
