Dont you know that you have more than 600 muscles in your body? They help you to do everything from pumping blood throughout your body to helping you lift your heavy backpack. You control some of your muscles, while others — like your heart — do their jobs without you thinking about them at all. If you take anatomic muscle map it will help you to learn that for instance there are three different types of muscles type of muscles.
Smooth Muscles
Smooth muscles — sometimes also called involuntary muscles, your brain and body tell them what to do without you even thinking about it. You can’t use your smooth muscles to make a muscle in your arm or jump into the air. But smooth muscles are at work all over your body. In your stomach and digestive system, they contract (tighten up) and relax to allow food to make its journey through the body. Your smooth muscles come in handy if you’re sick and you need to throw up. The muscles push the food back out of the stomach so it comes up through the esophagus (say: ih-sah-fuh-gus) and out of the mouth.
Smooth muscles are also found in your bladder. When they’re relaxed, they allow you to hold in urine (pee) until you can get to the bathroom. Then they contract so that you can push the urine out. These muscles are also in a woman’s uterus, which is where a baby develops. There they help to push the baby out of the mother’s body when it’s time to be born.
The muscle makes up the heart and called cardiac muscle. It is also known as the myocardium (say: my-uh-kar-dee-um). The thick muscles of the heart contract to pump blood out and then relax to let blood back in after it has circulated through the body. Just like smooth muscle, cardiac muscle works all by itself with no help from you. A special group of cells within the heart are known as the pacemaker of the heart because it controls the heartbeat.
Skeletal Muscles, sometimes called striated (say: stry-ay-tud) muscle because the light and dark parts of the muscle fibers make them look striped (striated is a fancy word meaning striped).
Skeletal muscles are voluntary muscles, which means you can control what they do. Your leg won’t bend to kick the soccer ball unless you want it to. These muscles help to make up the musculoskeletal system — the combination of your muscles and your skeleton, or bones.
It’s very interesting to learn to feel your own body, isn’t it?
