Ligament
Ligaments are strong fibrous cords composed mainly of collagen fibers which extend from one bone to another. They reinforce joint capsules and restrict unwanted movement. Capsular ligaments are distinct thickenings of the joint capsule. Extrinsic ligaments are found in the joint cavity connecting articular surfaces of the bones.
