A ligament joins muscle to bone

A ligament is made up of articular cartilage
- C.
Ligaments enable bones to move when muscles contract

Ligaments are tough, fibrous connective tissues that connect bones to other bones at a joint. They provide stability and support to the joint, preventing excessive movement and maintaining proper alignment. Ligaments do not join muscles to bones, as that is the role of tendons. Additionally, ligaments are not made up of articular cartilage, which is a smooth, slippery tissue that covers the ends of bones in a joint.Rate this question:
