Muscular system functions and their types

Muscles play a role in every function of the body. The muscular system consists of over 600 muscles. These include three types of muscles: smooth, skeletal and cardiac. Only skeletal muscles are voluntary, which means that you can control them consciously. Smooth and heart muscles act involuntarily. Each type of muscle in the muscular system has a specific purpose. You are able to walk because of skeletal muscles. You can digest because of your smooth muscles. And your heart beats because of my heart muscle. Read on to learn more about muscular system functions.


Different types of muscles also work together to make these functions possible. For example, when you are running (skeletal muscles), your heart is pumping harder (cardiac muscle) and causes you to breathe heavily (smooth muscles).

Your skeletal muscles are responsible for the movements you do. Skeletal muscles are attached to the bone and partially controlled by the central nervous system (CNS).


You use skeletal muscle when you move. Rapidly contracted skeletal muscles cause short pulses of speed and strength. Slow-systolic muscles work better during longer movements


Involuntary cardiac and smooth muscles help the heartbeat and blood flow through the body by generating electrical impulses. The cardiac muscle (myocardium) is found in the walls of the heart. It is controlled by the autonomic nervous system responsible for most of the body’s functions.


In muscular system functions, The muscle also has one central nucleus, such as a smooth muscle. Your blood vessels consist of smooth muscles and are also controlled by the autonomic nervous system.




Your diaphragm is the main muscle at work while breathing calmly. Heavier breathing, like what you experience during exercise, may require additional muscles to help your diaphragm. These can be abdominal, neck and back muscles.




The digestion is controlled by the smooth muscle located in the gastrointestinal tract. This includes:

#small and large intestines

In muscular system functions, The digestive system also includes the liver, pancreas, and gallbladder. Your smooth muscles contract and relax when food passes through your body during digestion. These muscles also help to push food out of the body through defecation or vomiting when you are sick.


Other muscular system functions



Smooth and skeletal muscles form the urinary system. The urinary system includes:

#penis or vagina

In muscular system functions, All muscles of the urinary system cooperate with each other, so you can urinate. The dome of your bladder is made of smooth muscles. You can release urine after tightening your muscles. When you relax, you can keep in your urine.




Smooth muscles are in the uterus. During pregnancy, these muscles grow and extend with the development of the child. When a woman comes into childbirth, the smooth muscles of the womb shrink and relax, helping to push the child through the vagina.




In muscular system functions, Skeletal muscles in your core help protect your spine and help you stay stable. Your muscle group includes the muscles of the abdomen, back, and pelvis. This group is also known as the trunk. The stronger your core is, the better you can stabilize your body. Muscles in your legs also help you keep your balance.

Your skeletal muscles also control your posture. Flexibility and strength are the keys to maintaining the correct posture. Stiff neck muscles, weak back muscles or strained hip muscles can dump your setting. Poor posture can affect parts of the body and lead to joint pain and weaker muscles. These parts include:

In The muscular system is a complex network of muscles necessary for the human body. Muscles play a role in everything you do. They control heartbeats and breathing, help to digest and allow movement.

Muscles, like the rest of the body, develop when you exercise and eat healthily. But too much exercise can cause muscle pain. Muscle pain can also be a sign that something more serious affects your body.

The following diseases can affect the muscular system:

myopathy (muscle disease)
muscular dystrophy
multiple sclerosis (MS)
Parkinson’s disease

Talk to your doctor if you have one of these conditions. They can help you find a way to manage your health. It is important to take care of your muscles so that they are healthy and strong.




 Skeletal muscles usually constitute at least 40 percent of body weight and are classified as vertical or axial depending on the location of the body. The big muscles of your arms and legs are simple skeletal muscles. Axial skeletal muscles include the muscles of the torso, head, and neck. Skeletal muscle contraction produces voluntary gross movements and minor, the primary function of the muscular system.

Gross movement refers to large coordinated movements, such as walking, running, jumping, sitting, standing up, lifting large objects, swimming and swinging a bat or rocket. Gross movements are mainly based on large skeletal muscles. Minor motor skills refer to smaller, more complex body movements. Examples include speaking, writing and playing a musical instrument. Minor motor skills usually involve small skeletal muscles of the hands, face or feet. Although the majority of skeletal muscles are under voluntary control, they can also contract by reflex – for example, Blinking, when the insect flies towards the face or detaches the hand from the hot surface.
