Why are they so important?
Muscles are very important. Without muscles it would be impossible to do anything. Muscles turn energy into motion. These motions take place when your brain tells your body to do something. Each muscle contains cells and these cells get energy from the food you eat. After they receive the energy needed they can contract and make you move.
There are voluntary muscles and involuntary muscles in your body. The voluntary muscles move whenever you tell them too. However, involuntary muscles move automatically by signals in your body through nerves and sometimes your brain. There are 3 main type of muscles in your body. They are skeletal muscles, smooth muscles, and cardiac muscles.
The skeletal muscles are muscles that adhere to the skeleton and we can usually feel these muscles. Skeletal muscles come in pairs; it has one muscle that moves the bone in one direction and the other muscles moves the bone in the opposite direction. Another type of muscle is the smooth muscle. The smooth muscle can be found in the digestive system, bladder, airways, the uterus and blood vessels. These muscles you can not physically see or feel.
The last type of muscle is the cardiac muscle. This muscle is found only in your heart. This muscle you can not see or feel physically. All muscles contract and relax. Muscles are considered the largest internal organ of the human body. So, why are these muscles so important you may ask.
Let's start with the first type of muscle. The skeletal muscles allow your body to move. Anything you do like sitting, walking, jumping, chewing, dancing, and even breathing involves the contracting of these muscles. Smooth muscles help support the organs, control blood pressure, determine the diameter of your pupils, and cause the hair on your skin to stand up. The cardiac muscles are obviously very important too. The cardiac muscles work with the cardiac cells to make your heart beat.
Hopefully by now you can see the important roles your muscles play in your life.
- The gluteus maximus or buttocks is the largest muscle in the body.
- The longest muscle in the human body is the sartorius. This muscle is in the front of your thighs and helps you to turn your leg.
- Approximately over 40% of your body is muscle mass.
- There are 30, plus muscles in your face.
- Your eye muscles get more work than any other muscle in your body. Approximately moving over 100,000 a day!
- Muscle does not weigh more than fat.
- Strongest muscle in your body is the masseter in relation to force. This muscle allows you to chew your food.
Funny that you always here muscle weighs more than fat, but that is simply untrue. A pound is a pound, but muscle is more dense than fat. This simply means that fat will take up more room than fat. You must exercise to keep your muscles healthy. Endurance and strength are two key ingredients for healthy muscles. In order to gain endurance you can walk or run to keep healthy. In order to get the strength then lifting weights must be done. This does not mean you have to lift heavy weights but it must be heavy enough to stimulate your muscles. I hope this helps you better understand the importance of muscles in our body. Peace, love, and blessings!
