What term is used to describe the movement in which the angle between body parts is increased?

• A. Extension
• B. Abduction
• C. Flexion
• D. Adduction

Answer: (A)

The term that describes the movement in which the angle between body parts is increased is "extension." This movement typically involves straightening a joint or segment, leading to a greater angle between the bones involved. For example, when you extend your arm at the elbow, the angle between the upper arm and the forearm increases. In the context of the other terms listed, “flexion” refers to decreasing the angle between body parts, such as bending the elbow. “Abduction” indicates a movement away from the midline of the body, while “adduction” describes moving a body part closer to the midline. Understanding these terms is crucial in fields like chiropractic, as they are fundamental to describing human movement and positioning.
