Which movement decreases the angle at a joint?

1. Extension

2. Flexion

3. Adduction

4. Abduction

The correct answer is: Flexion

Flexion is a movement that decreases the angle between two body parts at a joint. For example, when you bend your elbow or knee, you are performing flexion, which brings the two segments closer together and reduces the angle formed at the joint. This movement is essential in various physical activities and is often utilized in exercises and daily tasks, as it allows for more effective and efficient motion. Other movements listed, such as extension, increase the angle at a joint, while adduction and abduction relate to movements toward and away from the body's midline, respectively. Understanding these terms helps clarify how joints function in relation to physical movements.
