What prevent movable bones from getting out of place?

Ligaments are tough bands of connective tissue that connect bones to other bones. They help to stabilize joints and prevent them from becoming dislocated.

Tendons are tough bands of connective tissue that connect muscles to bones. They help to transmit force from the muscles to the bones, allowing us to move our bodies.

Joint capsules are fluid-filled sacs that surround joints. They help to lubricate the joints and prevent them from becoming damaged.

Muscles also help to keep bones in place by providing support and stability to the joints.
