What is the term for a joint position when it is bent at an extremity?

The term for a joint position when it is bent at an extremity is flexion. Flexion refers to the decreasing of the angle between two body parts, often occurring at joints such as the elbow or knee. For example, bending the elbow brings the forearm closer to the upper arm, reducing the angle between them, which is characterized as flexion.

In contrast, extension refers to the straightening of a joint and increasing the angle between body parts, abduction involves moving a limb away from the midline of the body, and adduction is the movement of a limb toward the body's midline. Understanding these terms is crucial in fields related to anatomy, kinesiology, and physical therapy, where precise movements and positions are integral to treatment and rehabilitation.
