high voltage electrical shocks produced maximum tension further increases in shock voltage produced little change in tension. explain the observation? Questions CONTR PANE ?1.Low voltageelectrical shocks VOLTAC produced no muscle tension. Why? 1.5 2. Increasing the voltage of single shocks applied to the muscle ERASE START llproduced contractions that increased in magnitude.

Explanation / Answer

Mild electrical shocks do not stimulate any muscle fibres to threshold for action potential production, that’s why muscle don’t contract and produce shock. Increasing the voltage further shows an increase in the number of contraction muscle fibres. The shock stimulated many muscle fibres to threshold for action potential production. a single twitch-type contraction of all the muscle fibres in the muscle, which allows to take up to a certain level of electricity to be activated and after that the twitching and contraction ceases.
