The cardiac muscle is found only in the heart, and it is responsible for pumping blood throughout the body. And last the skeletal muscle, it is the only muscle that is controlled consciously. Every physical action that a person performs (e.g. speaking, walking, or writing) requires skeletal muscle.

This “fight-or-flight” response is responsible for the physical reactions most people correlate with stress including increased heart ...
