Describe how you could increase the strength of the contract

Describe how you could increase the strength of the contraction with the isolatewd muscle, and explain how this is accomplished in vivo.

Solution

We can increase the strength of the contraction in an isolated muscle; if multiple places the muscle are stimulated at the same time, leading to a summation of the stimuli leading to increased contraction.

We can increase the strength of the contraction in vivo, as the muscle is stimulated repeatedly by nerves; more motor units are recruited to leading to more summation of contractions and hence increase in the strength of the contraction.
