In this post you will discover some interesting facts about the human muscles, but first I want to make sure you know, exactly what the muscles are. Basically they are the organs who allow us to move. They are made out of fibers. These fibers stretch and contract under the command of your brain. What holds the muscles to the bone is called tendon. When the muscles contract they pull the tendon, which pulls the bone and... you move.
Do you know that you have more than 640 muscles, which are separated in to two groups- Voluntary and Involuntary muscles
Voluntary are the muscles that you move whenever you want to do it, like your biceps for example.
Involuntary are the muscles that move without you thinking about it, like the heart. It contracts up to 80 times a minute and doesn't depend on whether you want it or not.
Now, when you know what muscles are, its time for the facts:
- The biggest muscle in the human body is the buttock muscle
- You use 17 muscles in order to smile, and 43 to frown
- When you move you use 200 muscles
- The strongest muscle in the human body is located in the jaw and its name is the the masseter muscle
- Your muscles are normally around 40-50% of your body weight
- Every half a kilo (1 lb) of muscle you gain, your body burns an extra 50 calories a day
- The fibers you already know about can support up to 1,000 times their own weight
- 75% of the muscle is water
- Producing the human speech takes 72 different muscles
- The human tongue consists of sixteen separate muscles, not one as many people think.
Something else you should never forget is taking care of your muscles. Make sure you exercise, warm up before challenging your muscles and provide enough protein so they could recover from a tough work out.
