NUR 203 Chapter Notes - Chapter 18: Posterior Tibial Artery, Scoliosis, Pectoralis Major Muscle
Document Summary
Musculoskeletal complaints and disorders are the leading cause of health care visits. Articular structures - include the joint capsule and articular cartilage, the synovium and synovial fluid, intra-articular ligaments, and juxta-articular bone. Articular disease - involves swelling and tenderness of the entire joint and limits both active and passive rom. Extra-articular structures - include periarticular ligaments, tendons, bursae, muscle, fascia, bone, nerve, and overlying skin. Ligaments - rope-like bundles of collagen fibrils that connect bone to bone. Tendons - collagen fibers connecting muscle to bone. Cartilage - another form of collagen, overlies the articular surfaces of the bone ends and facilitates smooth painless movement of the joint. Bursae - pouches of synovial fluid that cushion the movement of tendons and muscles over bone and other joint structures. Bones do not touch each other and ends are covered by articular cartilage and separated by a synovial cavity (cushions joint movement). Synovial membrane lines the cavity and secretes synovial fluid.
