Muscles

  1. 1. Your marvelous muscles What are the three types of muscles? How do we identify them? What do they do?
  2. 2. There are more than 600 muscles in our body! These muscles make up our muscular system . Our muscles are divided into 2 main groups In voluntary muscles Voluntary muscles
  3. 3. There are three (3) types of muscles in the human body <ul><li>Smooth - involuntary </li></ul><ul><li>Cardiac - involuntary </li></ul><ul><li>Skeletal - voluntary </li></ul>
  4. 4. Smooth muscles <ul><li>Smooth muscles help us move food through our digestive tract. </li></ul><ul><li>Involuntary means we don’t have to think about it, it happens automatically. </li></ul><ul><li>Smooth muscles are found in the digestive system </li></ul>
  5. 5. Think of a SMOOTH milkshake going down your throat to your stomach !
  6. 6. Cardiac muscles <ul><li>Cardiac muscles move blood around our circulatory system </li></ul><ul><li>Involuntary means we don’t have to think about it, it happens automatically. </li></ul><ul><li>Cardiac muscles are found in only one place in the human body … the heart! </li></ul>
  7. 7. To remember this name … just think of Valentine’s Day … when people share heart-shaped CARD S - CARD IAC
  8. 8. Skeletal muscles <ul><li>Skeletal muscles move all the body parts we choose to move </li></ul><ul><li>Voluntary means we choose to make these muscles move. </li></ul><ul><li>Skeletal muscles are found all over the human body. </li></ul><ul><li>Tendons attach these muscles to our skeleton </li></ul>
  9. 9. Most muscles work in pairs to cause movement <ul><li>One skeletal muscle pulls a bone one way, and its partner muscle pulls the bone the opposite way. One of the best-known skeletal muscles is the bicep . </li></ul><ul><li>A flexor is a muscle that causes a joint to bend when it contracts </li></ul><ul><ul><li>An extensor is a muscle that causes a joint to straighten when it contracts. </li></ul></ul>
  10. 10. Flexor - a muscle which bends a joint when it contracts. Your bicep is a flexor .
  11. 11. Extensor – a muscle which straightens a joint when it contracts. Your tricep is an extensor .
  12. 12. Now we are going to make a model so that we can see how it works! <ul><li>Muscle Maker instructions: </li></ul><ul><li>First, carefully cut out all three pieces along the solid black line </li></ul>
  13. 14. Wrap up … <ul><li>Turn to your partner and share … </li></ul><ul><li>What does involuntary mean? </li></ul><ul><li>What does voluntary mean? </li></ul><ul><li>How do voluntary muscles work? </li></ul><ul><li>On your slates … </li></ul><ul><li>Name the three types of muscles </li></ul><ul><li>Give an example of each type </li></ul>
