Skeletal system

• A joint is formed when two or more bones meet and are classified by how much movement is allowed.
• Articulating cartilage covers bones at a joint and prevents friction and a bursa is a fluid filled sac located between a bone and tendon bone that reduces friction.
• A joint capsule is a fibrous layer of tissue encasing the joint protecting and strengthening it. Synovial fluid fills the joint capsule nourishing cartilage and preventing friction.
• A synovial membrane is the inner lining to the joint capsule secreting synovial fluid. A pad of fat acts as a shock absorber.
• A ligament is fibrous connective tissue connecting bone to bone, holding structure and keeping them stable.
• A tendon is a fibrous connective tissue that attaches muscle to bone facilitating movement around a joint.
