Question

Quizplus · Accepted Answer

The elbow joint and a door on a hinge both move in a single plane. The elbow joint is a hinge joint, meaning it moves like a door on a hinge, with the humerus acting as the door and the ulna and radius acting as the hinge. The elbow joint allows for flexion and extension, just like a door on a hinge that can only open and close in one plane.
