  1. Muscular System Kendra Harris Christopher Dalton Kendall Singleton Deonte Spencer

  2. Muscular System Interaction with Nervous System • Receptors in muscles provide the brain with information about body position and movement. • The brain controls the contraction of skeletal muscle. • The nervous system regulates the speed at which food moves through the digestive tract Muscular System (in detail) • There are approximately 639 muscles in the human body. • Different types of muscles enable motion, generate heat to maintain body temperature, move food through digestive tract and contract the heart.

  3. Tendonitis • Tendonitis is the inflammation and irritation of tendons (cords of tough, fibrous connective tissue that attach muscles to bones and are found throughout the entire human body) • Anyone can develop Tendonitis, but it is more common in adults, especially those 40 years of age or older (tendons lose elasticity as they age)

  4. Tendonitis (cont’d) *Varies with severity* • Pain when the tendon is under pressure • Restricted movement • Weakness • (P)RICE • Anti-Inflammatory Drugs • Lasers • Ultrasound • Shockwaves Symptoms Treatments

  5. Myasthenia Gravis (MG) • A disease in which the immune system attacks the body's own tissues. • The attack occurs at the junction between nerve and muscle and targets the acetylcholine receptor (the part of a muscle cell that receives signals from a nerve cell) • Onset usually after age 40; young adults more likely to be women; older adults more likely to be men

  6. MG (cont’d) • Weakness in neck, arms, legs • Difficulty breathing, swallowing, talking • Drooping eyelids • Pyridostigmine(Mestinon) • Prednisone • Cyclosporine A • Plasma Exhange (PE) • Human immune globulin • Thymectomy Symptoms of MG Treatments

  7. Facioscapulohumeral Muscular Dystrophy (FSH) • Progressive muscle weakness and loss of muscle tissue that mainly affects the face, shoulder, and upper arm muscles. • It can affect muscles around the pelvis, hips, and lower leg. • Symptoms often do not appear until age 10 - 26, but it is not uncommon for symptoms to appear much later.

  8. FSH (cont’d) • Eyelid drooping • Inability to whistle • Decreased facial expression • Depressed or angry facial expression • Difficulty pronouncing words • Respiratory therapy • Physical therapy • Orthopedic appliances • Pacemaker (for cardaic abnormalities) • One small trial of Albuterol • One small trial of Creatine Symptoms Treatments

  9. Fibromyalgia Syndrome • A chronic disorder characterized by widespread musculoskeletal pain, fatigue, and multiple tender points. • Affects 3 to 5 percent of the general population • Occurs in people of all ages, even children • Men develop fibromyalgia too, although more women are diagnosed with it • Symptoms are chronic but may fluctuate throughout the day • Roughly one-quarter of people with fibromyalgia are work-disabled

  10. FS (cont’d) • Fatigue • Difficulty concentrating • Depressed mood • Increased bodily pain • Difficulty sleeping • Treatment Programs • Exercise • TricylicAntidepressants • Pain-Gone Pen • Trigger Point Injections Symptoms of FS FS Treatments

  11. How do you prevent these diseases? • Regular moderate exercise. • A diet low in saturated fats and cholesterol. • Ample amounts of quality protein and fiber. • Proper amounts of sleep. • Effective stress management
