Answer Stats
| Definition | Keyword | % Correct |
|---|---|---|
| A motor neurone and its muscle fibres | Motor unit | 82%
|
| Muscle fibres with a slow contraction speed and better adapted to lower intensity exercise EG long distance running | Slow oxidative | 71%
|
| Muscle fibres that fatigue quickly and used for highly explosive events EG 100m | Fast glycolytic | 57%
|
| When the strength of a contraction changes by altering the number and size of the muscle's motor units | Spatial summation | 53%
|
| 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 | All or none law | 50%
|
| Where there is a repeated nerve impulse with no time to relax so a smooth, sustained contraction occurs, rather than twitches | Wave summation | 50%
|
| When there is tension in a muscle but no visible movement | Isometric contraction | 44%
|
| These detect how far and how fast a muscle is being stretched and produce the stretch reflex | Muscle spindles | 44%
|
| A sustained muscle contraction caused by a series of fast repeating stimuli | Tetanic contraction | 41%
|
| Muscle fibres more resistant to fatigue and used where longer bursts of energy are needed EG 1500m | Fast oxidative glycolytic | 40%
|
| Where the motor neurone and the muscle fibre meet | Neuromuscular junction | 40%
|
| These are activated when there is tension in a muscle | Golgi tendon organs | 29%
|
| Where there is a sudden relaxation of the muscle in response to high tension | Autogenic inhibition | 25%
|
| Nerve cells which transmit the brain's instructions as electrical impulses to the muscles | Motor neurones | 25%
|
| Stretch -> Contraction -> Relax -> Stretch | Proprioceptive Neuromuscluar Facilitation | 1%
