Which term refers to the abnormal bending of a body part?

The term that specifically refers to the abnormal bending of a body part is flexion. In the context of anatomy and movement, flexion describes the action of decreasing the angle between two body parts, which can occur in joints like the elbow or knee.

When discussing abnormal bending, this can indicate movements that exceed normal ranges, potentially leading to strain, injury, or other pathological conditions. Flexion, as it relates to this question, essentially points to any scenario where the normal bending mechanics could turn into a harmful or maladaptive motion.

Other terms relate to different types of movements. Extension typically increases the angle between components of a joint, abduction refers to moving a body part away from the midline, and adduction means moving a part toward the midline. Understanding these movements is crucial in assessing normal and abnormal motions within the body.
