  1. The Muscular system

  2. What You’ll Learn • The major function of muscles • How to compare and contrast three types of muscles • How muscle action results in movement of body parts https://mrscameronswiki.wikispaces.com/file/view/superficial-anterior-muscles.jpg/61639556/superficial-anterior-muscles.jpg

  3. What you’ll learn/Vocabulary • Muscles: organs that relaxes and contracts to allow movement of bones and body parts • Voluntary muscles: muscles, such as face muscles, that can be consciously controlled • Involuntary muscles: muscles, such as diac muscles, that can’t be consciously controlled • Skeletal muscles: striated, voluntary muscles that muscles that move bones

  4. What you’ll learn/Vocabulary • Tendon: thick band of tissue that attaches muscle to bone • Smooth muscles: non-striated, involuntary muscles that move many internal organs • Cardiac muscle: striated, involuntary muscle that is only found in the heart

  5. Why It’s Important • The muscular system is responsible for how you move and the production of heat in your body. Muscles also give your body its shape. http://prometheus.med.utah.edu/~bwjones/C1276349108/E347011287/Media/Salt%20Lake%20Marathon%20start.jpg

  6. Moving the human body • A muscle is an organ that can relax and contract to allow movement. http://www2.fcsconline.org/staff/gradyt/muscular-anatomy-front.jpg

  7. Muscle control • Muscles that your able to control are Voluntary muscles. http://healthkut.com/blog/wp-content/uploads/2010/01/muscles-voluntary1.jpg

  8. Muscle control • Muscles that your NOT able to consciously control are Involuntary muscles. http://healthkut.com/blog/wp-content/uploads/2010/01/muscles-2.jpg

  9. Levers-Your Body’s Simple Machines • Muscles work like a simple machine called a lever. • Your body uses the three different types of levers for different movements. • First-class levers, second-class levers, and third-class levers are the three types of levers. http://lpc1.clpccd.cc.ca.us/lpc/DivisionIII/images/DSNT/Levers.jpg

  10. Types of muscle tissue • Skeletal muscle tissue: is attached to bones by tendons, is associated with the body's voluntary movements. It is a striated muscle. Unlike cardiac muscle, the cells are not branched.

  11. Types of muscle tissue • Cardiac muscles: it is found in the heart. Cells are joined to one another by infused discs which allow the synchronization of the heart beat. Cardiac muscle is branched, striated muscle. http://kentsimmons.uwinnipeg.ca/cm1504/15lab42006/CardiacMuscle.jpg

  12. Types of muscle tissue • Smooth muscle: is found in various parts of the body such as the arteries, the bladder, the digestive tract, as well as in many other organs. http://www.bergen.cc.nj.us/Faculty/rdill/Human_Bio/HB_lab_images/smoothmuscle1.gif

  13. Muscle action and energy • Glucose is restored by the blood stream. • Exercise = bigger muscles • No exercise = smaller muscles • Glucose = blood sugar • Whenever you move any of your body parts you muscles us an energy called glucose. • When bonds in glucose brake, the muscle retracts. • Muscles need to rest after all of glucose is used up. http://www.biochem.arizona.edu/classes/bioc462/462bh2008/462bhonorsprojects/462bhonors2007/gsantarelli/glucose.gif

  14. Muscles at work • Skeletal muscle movements are the result of pairs of muscle working together. http://www.shen-nong.com/eng/images/lifestyles/qigong/img14e.gif
