Question

Why can our elbow cannot move backwards

Answer 1

Answer:

Our elbow cannot move back because it has hinge joints which only allow back to forth movements.

In hinge joints, the articulating ends of the bones fit together like a hinge on a door, and movement is therefore restricted to flexion and extension, i.e. movement is only in one direction. The elbow joint is an example, which permits movement only in one direction, for example only in the forward direction.

Answer 2

Answer:

Our elbow cannot move backwards because the articulating ends of the bones come together like a hinge on a door, movement is limited to flexion and extension, or movement in just one direction, in hinge joints. The elbow joint is an example of a joint that only allows movement in one direction, namely forward. As a result, our elbow is unable to move rearward.
