Bones are what make up the skeletal structure in the body and keep it upright. They also serve the crucial function of protecting the soft organs in the body. The joints, or points at which two bones are fitted together, help keep the skeleton mobile. It enables bodies to move with fluidity and protects the bones and muscles from fractures and tears.

Bone and Joint Vocabulary
Bone any of the pieces of hard, whitish tissue making up the skeleton in humans and other vertebrates.
Joint a structure in the human or animal body at which two parts of the skeleton are fitted together.
Bone Marrow a soft fatty substance in the cavities of bones, in which blood cells are produced (often taken as typifying strength and vitality).
Ligament a short band of tough, flexible, fibrous connective tissue that connects two bones or cartilages or holds together a joint.
Vertebrates an animal of a large group distinguished by the possession of a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fishes.
Tendon a flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone.
Collagen the main structural protein found in skin and other connective tissues, widely used in purified form for cosmetic surgical treatments.
Cartilage firm, whitish, flexible connective tissue found in various forms in the larynx and respiratory tract, in structures such as the external ear, and in the articulating surfaces of joints. It is more widespread in the infant skeleton, being replaced by bone during growth.
Synovial Joint joins bones with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones' articulating surfaces
