muscle gaining secrets - The body's muscles

Muscles we have throughout the body and gives us the ability to keep us up and the ability to move us . The body has several types of muscle, skeletal muscle, sphincter muscles, smooth muscle and cardiac muscle. All of our more than 600 muscles are made ​​up of fibers. Each fiber is a cell with multiple nuclei which differs from the rest of the cells in the body that have a cell nucleus. It is so called myofibrils (bundles of fibers) which are the cause of the muscle fibers constricts (shrinks) and for example, we bend the arm or leg. Each myfibrill is divided into sarcomeres which are smaller segments. How strong the muscle has to do with how it is constructed and the number of sarcomeres. Musklens volume and length is less important.

Skeletal muscles are the muscles that we have control over and that helps us to move. Muscles attach to bones via tendons. The fibers can either tighten, stretch out and relax. Via the nervous system, we talk about the muscle what to do. When we are exposed to a hazard skeletal muscles act itself. We take for example your hand away from something that burned without us thinking about it. With this instinct we manage ourselves from many dangers in everyday life that may otherwise have drastic effects. Call muscles are used to open and close the openings in the body, only a portion of these muscle gaining tips, we have control over. Cardiac muscle is a muscle that we do not regulate consciously. Whether we think about it or will not hjärtmuskelaturen to work. Smooth muscle control we do not either. The smooth muscle is found in the intestines, bodkärl and lungs.

All motor muscles are antagonists, a muscle that counteracts another muscle. When you bend your arm work your biceps (the muscle on the front of your upper arm) when you then stretches out his arm again relaxes the biceps and triceps work (the muscle on the back of your upper arm). Biceps and triceps are Hence antagonists. Synergists are muscles that work together. Examples of synergists is your muscles at the front of the thigh where you have three muscles that work together. Synergists you in the places on the body where you need a lot of power as the thighs, buttocks, calf and shoulders. When practicing strength training, it is important to keep in mind to practice antagonists. Are you exercising for example, only the stomach but not the spine can cause problems with posture when your back can not compensate for the abdominals contractions. Synergists will often free when they trained together.
