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.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.

bal is blood alcohol level. bac will normally be higher in a person with more body fat. so the answer to your question would be, as body fat decreases, the increasing rate of bal decreases.
