What term describes the movement of a body part away from the midline of the body?

The term that describes the movement of a body part away from the midline of the body is abduction. This movement is fundamental in anatomy and kinesiology, often used in relation to limbs and digits. When an arm or leg moves away from the center of the body, it is described as being abducted. This is a key concept in understanding human movement and is frequently referenced in both medical and fitness contexts.

Adduction, in contrast, would refer to the movement towards the midline, which helps define the distinction clearly. Flexion and extension describe movements that change the angle between body parts, often related to bending and straightening joints. Understanding these terms is essential for anyone studying anatomy or working in a health-related field, as they provide the foundation for more complex movements and medical terminology.
