2. KEY KNOWLEDGEKEY SKILLS  The way the neuromuscular and musculoskeletal systems work together to bring about movements including major bones, muscles, joints and joint action  The various characteristics of the different muscle types – fibre and arrangement  Isotonic, isokinetic and isometric muscle contractions  The agonist and antagonist relationship as related to reciprocal inhibition and the associated use of stabilisers  The nervous control of muscles including recruitment of motor units, fibres and types of contraction.  Correct use of anatomical terms related to major bones, muscles, common joints and their actions that bring about movements  Participate in and analyse a broad range of movements used in sporting activities and be able to identify key bones, muscles and joint movements associated with those movements.  Explain and discuss how reciprocal inhibition works  Identify the different types of muscle fibres and contractions responsible for a wide range of physical activities performed at varied intensities. © Cengage Learning Australia 2011

5. Main functions of the Skeletal System 1. Protection of vital internal organs E.g. Rib cage protects heart 2. Support E.g. Posture 3. Attachment sites for muscles 4. Storage of fuels, fats and minerals 5. Leverage for muscles E.g. Allowing movement 6. Blood cell production E.g. Red (End of long bones) and White (Shaft of long bones) © Cengage Learning Australia 2011
