Document Summary

Sept 25 chapter 5: development and aging of body systems. Overview: developmental changes in the skeletal, muscular, adipose, endocrine, and nervous systems. Interaction of the systems: periods of change and external factors, as we age, genetic factors decrease and external factors increase, rate limiter anything holding back the development of motor actions. Body systems (individual structural constraints: body systems are influenced by extrinsic factors. Its important to know: the average pattern of change within each system, the range of individual variations for a system. Prenatal growth: the embryo has a cartilage model of the skeleton, ossification begins at primary centers in the midportions of long bones. In the womb there are 400 ossification centers (places where the bone is laid down and begins to be developed) Postnatal growth in the skeletal system: growth in bone length occurs at secondary centers at the ends of bones, these centers are called epiphyseal plates, growth plates, or pressure epiphyses.
