InnerBody explains that the human body contains three muscle types, which each perform a different function. The most obvious muscles are the skeletal muscles, which attach to tendons and move voluntarily, according to the Cleveland Clinic. Skeletal muscles produce body movements and maintain posture, allowing humans to sit, stand and walk. The Cleveland Clinic describes smooth muscles as those that line some of the body’s organs, and cardiac muscle as those that control the heart.Know More
In contrast to skeletal muscles, which are under voluntary control, cardiac and smooth muscles move involuntarily. Smooth muscles line the walls of many internal organs, such as the stomach and intestines, according to InnerBody. The smooth muscles, which are also called visceral muscles, help to pass food through the digestive system and other similar functions.
The University of California, Clermont, explains that the diaphragm is a smooth muscle that is at least partially under conscious control. While humans do not have to think to breathe, the diaphragm can be controlled, such as when people hold their breath.
All three types of muscles vary in appearance. Skeletal and cardiac muscles both possess striations when viewed microscopically. InnerBody states that these striations indicate that the muscles are strong. By contrast, smooth muscles lack such striations and are comparatively weak.Learn more about Muscles
The two major functions of the muscular system are the ability to make the body move and the posture of the body. The muscles enable the arms, legs and other parts of the body to move while keeping the body in an upright or sitting position without falling over.Full Answer >
The muscular system is fundamental to human life and humans would not be able to live without it. It is more than just a system that allows humans to move their limbs; it's also necessary for actions such as breathing, digestion and the pumping of blood around the body. The other functions of muscles include the movement of body parts, stability and heat production.Full Answer >
Exercise and good nutrition are essential to maintaining a healthy muscular system, according to Healthline. Strength training can slow the loss of muscle that accompanies aging, fortify muscle and connective tissue, increase bone density, reduce the chances of injury and ease arthritic pain, according to WebMD. Studies also show that strength training improves balance, reduces the risk of falling, helps control blood glucose levels and improves sleep and mental health.Full Answer >
The major types of muscle systems are the skeletal muscles, cardiac muscles and smooth muscles, explains Healthline. The skeletal muscles are voluntary muscles, whereas the smooth and cardiac muscles are involuntary ones.Full Answer >
