Abduction is:

1. Extending a body part

2. Moving a body part away from the body

3. Moving a body part toward the body

4. Rotating a body part

The correct answer is: Extending a body part

Abduction specifically refers to the movement of a body part away from the midline of the body. This term is commonly used in anatomy and movement science to describe actions such as raising the arms or legs to the side, moving them away from the center. In this context, it is essential to understand that the other choices describe different movements. Extending a body part refers to increasing the angle between body parts, which is known as extension. Similarly, moving a body part toward the body is referred to as adduction, which is the opposite of abduction. Lastly, rotating a body part involves moving it around its axis, which is a distinct type of motion altogether. Thus, the correct understanding of abduction is critical for accurate communication in health care and body mechanics.
