Transcript of "The muscular system"

  1. 1. Key Questions  How do we move?  What are muscles made up of?  What are the main muscles in our body?  What else do our muscles do for us?
  2. 2. How do we move?  Create a flow chart…
  3. 3. The muscular system functions  Support and posture Without the muscles, there would be no tension throughout the body to keep it upright.
  4. 4. The muscular system functions  Movement The voluntary muscles of our body (like the biceps and hamstrings) act on the bones they are attached to to produce movement
  5. 5. The muscular system functions  Involuntary bodily functions     Breathing Digestion Heart Beat The above functions are performed (or assisted by muscles) without thinking about them.
  6. 6. Muscles - structure  All of our muscles are made up of microscopic fibres, which when bundled together are called motor units.  These motor units (when called upon by a nerve impulse create movement.  The number of motor units used depends on the strength of the impulse and the effort (force) required
  7. 7. Which muscles should I know? Anterior Posterior  Pectorals  Trapizius  Biceps  Triceps  Abdominals  Latissimus Dorsi  External Obliques  Gluteus Maximus  Quadriceps   Tibialis anterior  Hamstrings Gastrocnemius
  8. 8. Key Concepts Review  The muscular system acts on the bones to allow us to move, breath, eat and more.  There are at least 700 muscles in the human body which perform a wide variety of voluntary and involuntary functions  The muscles are made up of bundles of muscle fibres, which the body uses to different degrees based on the demands of a task.
