A hinge joint primarily allows which type of movement?

• A. Rotary movement
• B. Gliding movement
• C. Circular movement
• D. Swinging movement (flexion or extension)

Answer: (D)

Hinge joints move in one plane, allowing bending and straightening. This swinging movement corresponds to flexion and extension around a single axis, as seen at the elbow or knee. It doesn’t involve turning around an axis (that would be rotary movement at a pivot joint), nor does it create a circular path (circumduction seen at ball-and-socket joints), nor a sliding action between flat surfaces (gliding). So the primary movement of a hinge joint is swinging—flexion or extension.
