Which movement is described as moving a joint away from the body?

The movement described as moving a joint away from the body is known as abduction. This term derives from the Latin "abducere," meaning to lead away from. In the context of anatomy, abduction refers to the action of moving a limb or a body part laterally or outward, away from the midline of the body. For example, when you raise your arm out to the side, you are performing abduction at the shoulder joint.

Conversely, adduction is the movement that brings a limb closer to the midline, which distinguishes it clearly from abduction. Extension and flexion refer to movements that involve increasing or decreasing the angle between body parts, typically in relation to the joints, and do not pertain to the movement away from the body.
