our elbow cannot move backwards because the elbow has only hinge joint that allow movement only in one direction
Our elbow joint allows bending and straightening but limits backward movement to prevent overextension. The joint consists of bones, ligaments, and muscles designed to restrict motion beyond a certain range. This limitation ensures stability, preventing injuries that might occur if the elbow were to move backward excessively. It safeguards the joint’s health and functionality during daily activities.
