Clues

  • a sustained muscle contraction caused by a series of fast repeating stimuli (7, 11)
  • nerve cells which transmit the brain's instructions as electrical impulses to the muscles (5, 7)
  • refers to exercise that is of a high intensity such as sprinting, where the demand for oxygen by the muscles cannot be met. so basically exercise without oxygen. (9)
  • these are activated when there is tension in a muscle (5, 6, 6)
  • these detect how far and how fast a muscle is being stretched and produce the stretch reflex (6, 8)
  • when the strength of a contraction changes by altering the number and size of the muscle's motor units (7, 9)
  • 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)
  • where the muscles have become bigger and stronger (11)
  • where there is a repeated nerve impulse with no time to relax so a smooth, sustained contraction occurs, rather than twitches. (4, 9)
  • 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)
