The force of muscle contraction is controlled by multiple motor unit summation or recruitment. True or False

The correct answer is "True".

Explanation:

It is true that the force of muscle contraction is controlled by multiple motor unit summation or recruitment. A motor unit is defined as the sum of a motor neuron and the skeletal muscle fibers innervated within it. The force of muscle contraction depends not only on a motor unit, but to multiple motor unit summation or recruitment that are activated at the time of contraction.

True.

Explanation:

Particularly skeletal muscles contraction are controlled by moton neurons by action potentials. The contraction of muscles which are neurogenic can be describes as summation, twitch, or tetanus, it depends on the action potential frequency.

In simple words, our nervous system generates a signal in the form of impulse which travels by action potential through a nerve cell called motor neuron. This signal causes the contraction of muscle fibers and when this signal terminates the muscle fibers come back to normal relax position.

So, its true that the force of muscle contraction is controlled by multiple motor units summation or recruitment.

dude i stopped reading after the first 7 words but hey you seem real smart thats awesome have a great day

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
