One of the chief functions of the muscular system is the production of heat. This is important for the maintenance of homeostasis (maintaining a stable consistent internal environment). Body temperature must remain within an acceptable range or face adverse physiological consequences. Muscle fibers generate heat by sliding against one another in the sliding filament theory/model.

Of course, another apparent function is movement. Skeletal muscles attach to the skeleton. When we move our bodies muscles with the assistance of tendons and ligaments help pull the bones in the direction we want to move. Additionally, the heart is composed of muscle and without a functioning heart everything else is fruitless.

Muscle tissue also stores needed energy in the form of glycogen, this is a reserve energy source that the body utilizes when called upon.

The muscular system plays several roles in the human body. It is essential for locomotion, balance and posture, absorbing shock and heat, breathing, and digesting food. These are just a few of the important functions that are performed by the muscular system, there are many more. If our bodies did not have muscles, we would not be able to move or even breathe and our hearts would not be able to circulate blood throughout the body. For all of these reasons, the muscular system is vital.

There are three types of muscles. Cardiac muscles are found in the heart. Smooth muscles (involuntary) are controlled by the autonomic nervous system. Skeletal muscles are attached to bones and allow us to move.

Without the muscular system we wouldn't be able to move, at all.  We would be no different than a plastic skeleton hanging up in a biology class that is covered in a layer of dermis.  Furthermore, all the major organs in our bodies like our heart and stomach are also muscles, without them we wouldn't be able to survive in the capacity that we do now at all.  Our muscular system functions to give us mobility, produce heat, absorb the shock of our falls, create a shape to our body, respirate, swallow and digest our food, and pump blood through our bodies.  Without it, we would not survive as an organic being.

There is no particular main structure of the muscular system though the one that often first comes to mind is our skeletal muscles - the muscles that give us mobility and strength.  They are our voluntary muscles.  After that people usually thinking of our cardiac muscles that circulate blood through out bodies, and finally the smooth muscles that make up our internal organs like our stomach, throat, intestines etc.  Both the cardiac and smooth muscles are involuntary, we do not consciously choose to make them go, but instead they go on autonomically.
