Are relaxation of a muscle and inhibition of a muscle the same thing? Explain your answer.
What will be an ideal response?
No. Relaxation is a passive process that normally follows contraction and occurs in the absence of further activity in the motor neurons. Inhibition involves prevention of muscle stimulation and consequent contraction by activity in interneurons that inhibit motor neurons. While in both cases the motor neuron is not producing signals, the reason is lack of stimulation in one case, inhibition in the other.
