What is a joint?
A joint is the connection between two bones. The connection is typically stabilized by multiple tendons, ligaments, and often a collagen capsule. At the ends of the two bones are slick, shock absorbing layers of articular cartilage. When the cartilage wears out, the joint becomes arthritic, which results in stiffness and pain.
What is a tendon?
A tendon is a thick fibrous band of collagen fibers that connects a muscle to a bone. This firm attachment transmits the force of the contracting muscle to the bone, resulting in motion of the joint.
What is a ligament?
A ligament is a thick band of collagen fibers that connects a bone to another bone, imparting stability to the joint between the bones.
