What is the action described as external rotation at the shoulder and hip joint?

The action described as external rotation at the shoulder and hip joint involves rotating the articulating bone away from the body's midline. In the context of the shoulder joint, external rotation occurs when the arm is positioned such that the elbow is bent at 90 degrees and the forearm is rotated outward, away from the body. Similarly, for the hip joint, external rotation involves turning the thigh outward, moving the knee away from the body. This movement is essential for various activities, including sports and daily functional tasks, as it contributes to the range of motion and stability of the joints. The description of external rotation as turning away from the body is key to understanding how these movements facilitate actions such as throwing and kicking.
