Physioex 8 0 exercise 2 skeletal muscle physiology

The muscle will produce force for a longer period if the stimulator is briefly turned off than if the stimulations were allowed to continue without interruption.

Motor unit recruitment refers to You correctly answered: a. Describe the process of excitation-contraction coupling in skeletal muscle fibers. An action potential in a motor neuron triggers the release of which neurotransmitter? What happened in the isolated skeletal muscle when the maximal voltage was applied?

Common reasons: Disagreement on rewards. Specifically, what happened to the muscle force generated with stronger electrical stimulations and why did this change occur? Does the duration of the latent period change with different stimulus voltages?

Your answer: the change in the whole-muscle force was achieved in vivo where additional motor units are recruited to increase the total muscle force produced basically.
