How would people move if they didn't have joints?

If people didn't have joints, movement would be severely limited or impossible. Joints are the connections between bones that allow for bending, twisting, and extending movements. Without joints, the skeletal system would be rigid and immobile, greatly impairing basic functions such as walking, reaching, and even breathing. Movement is facilitated by muscles pulling on bones at joint locations, so without joints, muscle function would also be severely compromised.
