Muscles allow a person to speak, and chew. They control heartbeat, breathing, and digestion. Other seemingly unrelated functions, including temperature regulation and vision, also rely on the muscular system.
But there’s much more to your muscles than that. To find out more about the muscular system, check out this 10 fun, also amazing facts.
- There are more than 600 muscles in the body. Muscles make up 40% of your total body weight.
- The word muscle is derived from the Latin term musculus, meaning “little mouse”. This Latin term could be due to the shape of some muscles or because muscles contracting under the skin can look like a mouse moving under a rug.
- There are 3 types of muscles, includes skeletal muscles, smooth muscles, and cardiac muscles.
- Smooth muscles are the involuntary muscles in your gut, blood vessels, and elsewhere that work without you consciously thinking about making them move.
- Skeletal muscles are attached to the bone and help you with everyday activities ranging from sitting and standing to walking, typing, and doing housework.
- Cardiac muscles are in your heart. This muscle works all by itself with no thought. And the only muscle that never tires is our heart.
- Smooth muscles in a woman’s uterus, which is where a baby develops and grows, push the baby out when it’s time to be born.
- The smallest muscles are found in the middle ear. The gluteus maximus is the largest muscle in the human body.
- To take one step, you use 200 muscles. It takes 17 muscles to smile and 43 to frown.
- The strongest muscle is in our jaw and is used for chewing. If all of the muscles in the body could pull in one direction, it would create a force of 25 tons.
- Your eye muscles move more than 100,000 times a day. Blinking is a muscle contraction that takes place more than 16,400 times a day.
- Muscles provide body heat and not just a little bit. Your muscles create at least 85 percent of your total body heat. When muscles contract, they put off some serious warmth. This is why you shiver when you are cold.
Muscle memory is created by practicing an action over and over again. Our muscles fine-tune themselves, becoming more precise and exact in what they do. So practice is very important when learning a sport!
