The term that describes the bending motion that decreases the angle between adjoining bones is flexion. This occurs when two bones move closer together at a joint, resulting in a decrease in the angle between them. For example, when you bend your elbow, the angle between the forearm and the upper arm decreases, demonstrating flexion.

Flexion is typically associated with movements such as bending the knee, elbow, or hip, where the flexing action is clearly observed. It is important to understand this concept as it plays a critical role in both basic human movements and therapeutic exercises aimed at increasing joint mobility and strength.

The other options describe different types of movements. Extension is the opposite of flexion, involving a straightening motion that increases the angle between bones. Rotation refers to the action of turning around an axis, and abduction involves moving a limb away from the midline of the body. Understanding these distinctions helps clarify the types of movements that joints can perform.
