Chapter 37: Structural Support and Movement I. Types of Skeleton 1. Hydrostatic has muscle cells that apply the force of contraction against a body fluid and redistribute in a confined space 2. Exoskeleton is rigid to accept applied force of contraction 3. Endoskeleton is internal body parts such as bone II. Vertebrae Skeletons A. Vertebrae are bony segments of a backbone that extends from the base of the skull to the pelvic girdle. B. Intervertebral disks are cartilaginous shock absorbers that can cause chronic back pain when ruptured or slipped out of place III. Bones and Joints A. Red marrow is the site of blood cell formation and fills the spaces in spongy bone B. Yellow marrow is the central cavity in most mature bones of adults C. Bone remodeling occurs when osteoblasts help form new bone tissue which makes up for bone tissue in osteoclasts breaking them down. IV. Skeletal-Muscular System A. Muscle fibers are skeletal muscle cells that fuse together into one multinucleate B. Myofibrils are bundles of contractile filaments that run from one end of the fiber
