As the name suggests, the Muscular System consists of all the muscles that regulate and support various functions and movements of the body.
It is one of the most important organ systems in the human body that not only supports the whole skeleton system but also contributes to the overall weight, shape, and appearance of the body.
Muscles are either voluntary or involuntary. Voluntary muscles can be controlled by us while involuntary muscles keep on working on their own without our conscious effort.
Muscular System Types | Muscular System Parts
Almost 600 muscles of different shapes and sizes are in the whole skeletal system of the human body. These muscles work in tandem with the nervous system to receive signals from the brain and help in the smooth movement of the various parts of our body.
They protect the bones and keep them in place while allowing proper movement and other functions.

Muscular System Functions
- Muscular System helps in the proper movement of all the associated parts in our body.
- It System helps us in maintain proper posture and balance while performing various tasks.
- Muscular System keeps our body warm.
- It System is a major contributor to our overall strength
Three Types of Muscles
All types of physical activities such as walking, pushing, running, or even talking require muscular movements that are controlled consciously by us. Skeletal muscles help us in performing these tasks.
As these muscles have striations that can be easily seen under a microscope, we also call them striped or striated muscles. Skeletal muscles contract and expand to move parts of the attached bones and facilitate easy movement.
In this process, the muscles become strong and straight therefore they are often called straightened muscles as well.
These are non-striated muscles working without our cognizant command over them. Along these lines, we call them compulsory muscles. Otherwise called instinctive muscles, they help different indispensable organs like the intestinal system, veins, and secretory pipes in smooth working.
These muscles help our internal organs such digestive tract in moving food and waste through the track. We hardly notice this movement in our body as they work without our conscious effort and are controlled entirely by smooth muscles.
Not at all like skeletal muscles which are somewhat sinewy packs, smooth muscle structure a stringy sheet that wraps the encompassing organs. One more illustration of smooth muscle work is squinting of eyes which are constriction and development of the students.
There are many other movements except the movement of the heart, that are controlled by these muscles.
Our heart starts beating well before we are born and it stops working only when we die. This consistent heartbeat all through our life is controlled automatically by a gathering of muscles called cardiovascular muscles.
These are constrained via Autonomic Nervous System which directs different capacities too with the goal that our body can perform different errands. Cardiac muscles keep on working no matter what, even if we are unconscious for any reason.
When a muscular system stops working properly, it results in various ailments such as Duchenne Muscular Dystrophy and Myasthenia gravis. The best way to prevent muscular diseases is to take regular exercise in any form so that all the muscles can function properly.
