Explanation

The elbow joint functions as a hinge joint, allowing movement primarily in one plane (flexion and extension - bending and straightening). Hinge joints are like door hinges, permitting back-and-forth movement in a single axis. The knee is another example of a hinge joint, distinguishing it from ball-and-socket (hip/shoulder), pivot (neck), and gliding joints (wrist/ankle).
