(9) 6. refers to exercise that is low to medium intensity where the oxygen demand of the muscles can be met. so basically exercise with oxygen. (7) 7. where a sequence of impulses has to be of sufficient intensity to stimulate all of the muscle fibres in a motor unit in order for them to contract. if not, none of them contract. (3, 2, 4, 3) 9. a motor neurone and its muscle fibres (5, 4) Down 2. these detect how far and how fast a muscle is being stretched and produce the stretch reflex (6, 8) 3. nerve cells which transmit the brain's instructions as electrical impulses to the muscles (5, 7) 4. where there is a repeated nerve impulse with no time to relax so a smooth, sustained contraction occurs, rather than twitches. (4, 9) 5. where the muscles have become bigger and stronger (11) 7. where there is a sudden relaxation of the muscle in response to high tension. the receptors involved in this process are Golgi tendon organs (9, 10) 10. these are activated when there is tension in a muscle (5, 6, 6)
