  1. The Muscular System Cindy Quisenberry

  2. Functions of the Muscles • What is the major function of the muscles? • Movement – walking, running, etc. • Digest Food • Pumps blood throughout your body • Provide stability • Movement of substances (ie: urine) • Help control body temperature

  3. Types of Muscles • Involuntary - muscles govern movement that is not controlled by will, such as respiration and digestion. • Involuntary muscles that move the internal organs and systems are called smooth muscles. • Cardiac - controls the contractions of the heart. • Also an involuntary muscle • Voluntary - muscles can be contracted at will. • Also called skeletal muscles

  4. Skeletal Muscles • Provide movement • Help maintain posture • Protect internal organs • Produce heat and energy for the body

  5. Bursa • a sac lined with a synovial membrane that helps the movement of joints

  6. Movement takes place at the joint and uses the: • Muscles • Ligaments • Tendons

  7. Review .

  8. ___________________are involuntary muscles. Muscles that act on the lining of the body’s passageways and the hollow internal organs

  9. ______________________is involuntary and is responsible for the contraction of your heart. Your heart beats 100,000 times each day. A type of striated muscle that forms the wall of the heart .

  10. Most of your muscle tissue is skeletal, and almost all _________________ are under voluntary control. Muscles attached to bone that cause body movements

  11. Musculoskeletal Structure • Tendons – anchor muscles to bone • Bursas – lie between some tendons and the bones beneath them. Bursas are lined with synovial fluid – making it easier for the tendon to slide over a bone when the tendon shortens

  12. Musculoskeletal Structure • What would the term be for inflammation of the bursa? • What would the term be for inflammation of a tendon?

  13. What Muscles Do Skeletal muscles work in pairs to produce movement.

  14. Caring for Your Muscles Get regular exercise. Eat high protein foods to build muscle. Practice good posture to strengthen back muscles. Use proper equipment and wear appropriate clothing to protect muscles during any physical activity. Warm up properly and stretch before exercising, and cool down after exercising to prevent injury.
