What does the term 'dorsiflexion' specifically refer to?

Dorsiflexion specifically refers to the movement of the foot where the toes are raised upward toward the shin. This action occurs at the ankle joint, decreasing the angle between the dorsum (the top) of the foot and the leg. It's a key movement in walking, running, and various physical activities, enabling the foot to clear the ground during the swing phase of gait.

The other movements listed involve different joints and actions that do not relate to the positioning of the foot. For instance, bending the knee involves flexion at the knee joint, bending the wrist deals with wrist flexion or extension, and bending the elbow pertains to flexion at the elbow joint. Each of these motions occurs in different parts of the body and serves different functional roles in movement and stability.
