1. Muscle is a tissuecomposed of bundles ofelongated cellscapable ofcontractionand relaxation to producemovementin an organ or a part of the body.
2. Muscles are very important for two major reasons:1. Muscles are the "engine" that our bodies use topropelourselves. They turn energy intomotion. 2. It would be impossible for you to do anything without your muscles.
3. Muscles simply moveyou! Without muscles you couldn't open your mouth, speak, shake hands, walk, talk, or move your food through your digestive system. There would be no running, climbing, smiling, blinking and breathing. The fact is, without muscles, you wouldn't be alive for very long.
4. On average, 40% of your body weight is in muscles. You have over 650 muscles that move you.
5. The cells that make up muscles contract and then relax back to original size. The cells of your muscles use chemical energy from the food you eat to do this. Without food, and particular kinds of nutrients, your muscles wouldn't be able to make the energy to contract. Muscles can be voluntary and involuntary. Voluntary muscles are muscles that you can move whenever you want to. Involuntary muscles contract and relax automatically inside your body. We cannot control our involuntary muscles.
6. Yes. If you hear someone says that they have "pulled" a muscle, they have, in fact, torn a muscle in the same way that you can tear a ligament or break a bone. And, like other living body parts, they generallymendthemselves.
7. There are three types of muscles: striated muscles, smooth muscles and cardiac muscles. Smooth muscles make up the walls of the internal organs and control their movement. They are involuntary muscles. Striated muscles move bones. They muscles work in pairs. When one contracts, the other relaxes. These muscles areattached to bone bytendons. They are voluntary muscles. Cardiac muscles make up the heart and control its contractions.
