Session 8

  1. 1. Anatomy & Physiology for Sport ‘Muscular System’ Session 8
  2. 2. Session Aim/Objectives <ul><li>Session Aim – To understand the muscular system in more detail to complete tasks 5 & 6 </li></ul><ul><li>Session Objectives </li></ul><ul><li>Everybody will describe what muscles are </li></ul><ul><li>Some will list & understand different muscle types </li></ul><ul><li>Most will identify the major muscles of the body & the location of these muscles </li></ul>
  3. 3. What are Muscles? <ul><li>Muscles are the fleshy bits that move the different parts of your body, inside and outside. </li></ul><ul><li>Muscles are made of fibres. Each fibre is made up of long thin cells which are packed in bundles. </li></ul><ul><li>More about muscle fibres next session </li></ul>
  4. 4. Types of Muscles <ul><li>There are three types of muscles found in </li></ul><ul><li>the human body: </li></ul><ul><li>Cardiac Muscle </li></ul><ul><li>Smooth Muscle </li></ul><ul><li>Skeletal Muscle </li></ul><ul><li>Where do we find each type?? </li></ul>
  5. 5. Cardiac, Skeletal & Smooth
  6. 6. 1. Cardiac Muscle What happens when the coronary arteries become blocked? <ul><li>The cardiac muscle works without you thinking about it - there is no conscious control. </li></ul><ul><li>Even when asleep it is capable of constant, automatic and rhythmical contractions. </li></ul><ul><li>It is only found in the walls of the heart, which has its own blood supply provided by the coronary artery. </li></ul><ul><li>When it contracts, the heart pumps blood to the lungs and around the rest of the body. </li></ul>The person will suffer a heart attack, as the cardiac muscle of the heart needs a constant supply of oxygen to keep contracting (beating). If immediate medical attention is not given the person will die. Question: Answer : Coronary Artery
  7. 7. 3. Voluntary Muscle <ul><li>You have full conscious control over voluntary muscles. However they can also be involved in involuntary reflexes. </li></ul><ul><li>They are also know as striated or skeletal muscle. </li></ul><ul><li>They are attached to bone and cause the skeleton to move. </li></ul><ul><li>Examples include the triceps and hamstrings. </li></ul><ul><li>They are the largest group of muscles in the body. </li></ul>
  8. 8. 2. Involuntary Muscle Artery Vein Small Intestine <ul><li>Involuntary muscle works without you thinking about it - there is no conscious control. </li></ul><ul><li>Also know as smooth muscle. </li></ul><ul><li>Found in the walls of arteries, veins, stomach and intestine. </li></ul>
  9. 9. Drag each label to the correct place on the body… Body Muscles - Front
  10. 10. Body Muscles - Back Drag each label to the correct place on the body…
  11. 11. Task 1 <ul><li>Complete the worksheet ‘major muscles’ </li></ul><ul><li>Identify every muscle </li></ul>
  12. 14. Conclusion <ul><li>The 3 types of muscles in the body include……………………………….. </li></ul><ul><li>How might you describe each type of muscle? </li></ul><ul><li>Name 10 muscles in the body! </li></ul>
