Question

3. Why can't our elbows bend backwards?​

Answer 1

Explanation:

Structurally joints don't bend both ways because there are physical components within their design that prevent or resist motion. This could be bone, such as the elbow joint, or it could be ligamentous restraint, such as in the knee. All joints in the body are a compromise between mobility and stability.
