Chapter Summary

• Muscles allow movement, stability, control of body openings, production of heat

  ​

• Muscle tissue - skeletal, visceral, cardiac

  ​

• Muscles create energy - creatine phosphate and stored glucose

  ​

• Major skeletal muscles - head, upper extremities, abdomen, pectoral girdle, lower extremities​

​-Common diseases of aging - arthritis, fractures, osteoporosis, muscular decline​

-There are many common disease and disorders of the muscular system with varied sighs, symptoms, and treatments
