What are the types and functions of our muscles? | HEALTH




Muscles in the human body account for about 40% of a person's weight with gluteus maximus in the buttocks being the largest muscle in the body. There are various types of muscle in our muscular system and each play a crucial role in the overall function of the body. Muscles control heartbeat, breathing, and digestion. They allow a person to chew, speak, and of course, move. Other seemingly unrelated functions also rely on the muscular system, including vision and temperature regulation.

To enable the full functioning of the body, there are 600 muscles that work together. These muscles are divided into three types:


Cardiac muscle

Our cardiac muscle is strong and acts involuntarily. It is located only in the heart and pumps blood around your body. It stimulates its own contractions, which is controlled by signals from the nervous system, forming your heartbeat.


Smooth muscle

Smooth muscle, also known as visceral muscle, is the weakest type of muscle. It acts involuntarily, which means it cannot be consciously controlled.

However, despite being weak, it has a crucial role in and maintaining blood circulation through the blood vessels and moving food along the digestive tract. It lines the inside of blood vessels and organs.


Skeletal muscle

Of all the muscles, skeletal muscles are the only ones that can be controlled consciously. Because they are attached to bones, they cause movement when they are contracted. So, any physical action that you consciously do involves the use of skeletal muscles.
