Question

Neural control affects the maximal force output of a muscle by determining which and how many motor units are involved in a muscle contraction and the rate at which the motor units are fired. These two factors are known as what, respectively?

a. rate coding; EMG
b. EMG; firing rates
c. recruitment; rate coding
d. firing rates; recruitment

Answer 1

Recruitment; rate coding.

Step-by-step explanation:

Muscle is one of the important tissue of the body that helps in the movement of the body. Cardiac muscle, smooth muscle and skeletal muscle are three different types of muscle.

The muscle has the ability to change its contraction force depends upon the two factors. The rate coding adjusts the firing of the neural muscle rate while travelling down to the motor neuron via the central nervous system. The motor unit recruitment is the way bu which the number of different units recruited in a particular task can be altered.

Thus, the correct answer is option (c).
