1. UNDERSTANDING MUSCLE Flex your body… flex your brain

2. Agenda  Actin and myosin gets the message  The magic of ATP  Types of muscle geometry  Types of muscle roles  ID and tag muscles

3. Actin and Myosin  http://www.youtube.com/watch?v=gJ309LfHQ3M http://www.youtube.com/watch?v=gJ309LfHQ3M  Let’s build an axon and motor unit

4. ATP the magic fuel  How is ATP delivered to the muscle fibers.  Aerobic  Anaerobic (LA system)  Anaerobic (CP system)  Let’s have a look at how that works

5. Muscle Design  Geometry  Relationships with each other  Types of fibers

12. Muscle roles  Agonist  Antagonist  Synergist  Fixator

13. Example: Arm flexion at the elbow  Agonist?  Biceps brachii  Antagonist?  Triceps brachii  Synergist  Brachialis  Fixator  Deltoid

14. Muscle charting  In groups of 5 complete the following tasks:  Use the provided sticky notes to label one member of your group with the muscles listed  Using the provided chart, complete all the information for each muscle  Have your “patient” lay on one of the desks  What do you notice about each of the muscles?  What would happen if you patient stayed this way for 2 weeks?
