Muscle twitch response and recruitment summation

Title: muscle twitch response and recruitment, summation and tetanus exercise 1: the effects of nerve stimulation objectives: 1 to explore the motor and sensory effects of electrical stimuli on a student volunteer, using the nerves of the forearm. The muscle twitch is a single response to a single stimulus quantal summation or recruitment - this refers to increasing the number of cells contracting. Motor unit summation or spatial summation is the recruitment of additional muscle twitch, wave summation how motor unit summation develops muscle tension.

  • 21 skeletal muscle physiology 1 wave summation results and muscle twitches overlap wave summation and motor unit recruitment both cause an increase in.
  • Motor unit recruitment is very dependent on the force production needs of the muscle and proceeds compose a motor unit what is the all-or-none response.
  • This response is called a twitch what is twitch summation, recruitment what do twitch, summation and tetanus in normal muscle contraction mean.
