Voluntary Muscle Movement

Introduction to voluntary muscle movement:

Muscle movements are primarily of two type’s i.e.

•    Voluntary muscle movement

•    Involuntary muscle movement

Voluntary muscles basically refer to those types of muscles, which respond to our will. These muscles act whenever we want them to act. Many examples can be moving of leg, winking of eyes etc.


Examples on voluntary muscle movement:


We can use our limbs both fore limbs i.e. hands and hind limbs i.e. legs as we want them to use. An example would make it lot clearer. Consider a sprinter who wishes to participate in a race. As soon as the pistol bangs, he should start sprinting in order to be part of the racing sport. Now here the sprinter is in command of his hind limbs i.e. the legs and the legs respond to his will. So we can see that voluntary muscles can be fully controlled by our wish. Another example can be of an archer who points an arrow at the bull’s eye. The banging of the revolver sends a message to his brain and he shoots the arrow at the bull’s eye. Here again we see that the fore limbs are in his full control.


voluntary muscle movement: conclusion:


Thus any action which stimulates our body parts to take action both aggressive and defensive is called as voluntary in nature, and the muscles detrimental in achieving the same are called voluntary muscles. This is in complete contrast to the involuntary muscles on which we have no command. Examples could be pumping of heart, the respiratory system. One can’t regulate the heart, or the respiration. These actions are said to be involuntary in nature. Basically one can say all the internal organs right from the flow of blood in our veins to the ultra filtration of blood in the kidney can be classified as involuntary, rest all the actions can be termed as voluntary in nature.
