How many muscles of the human body
The human body contains 206 bones including 22 bone found in the human skull, but if we dealt with the muscle and that's what we'll talk about it, we find that the human body contains 620 different muscle, the most powerful masseter muscle between the jaws, and the largest thigh muscle. If you look at the muscle in your sleeve you'll find it a powerful and flexible fabric makes the body move. In the daily life of human muscle is used in various types of movement, when eating jaw muscle used for chewing food, and help other muscles in turning food into the stomach or intestines, and chest muscles make breathing possible. Muscle covering all the human body, and when growth is increasing muscle size, at puberty become muscle half body weight. Muscle muscle types are divided into two basic types; structural and other smooth muscles, and is at the heart of its own muscle combine skeletal muscle and smooth. Skeletal muscle skeletal muscle functions of the cohesion of the bones of the structure. Give shape and mainstay. Move the body. Skeletal muscles constitute the bulk of the legs, forearms, abdomen, chest, neck and face. Skeletal muscle formation muscle is made up of cells called fibers, fiber be at long cylindrical shape, if you look at it within the microscope you will see a dark package share with whiter package called Altakttat, and therefore also called on skeletal muscle striated muscle name. Fiber connected to each connective tissue, are associated with the end of the muscle-bone connective tissue strong, too. Skeletal muscle skeletal muscle works in two ways way of working, they are working in duplication: flexor: where to bend the joint party and come close to the body. Extensor: The contrast to the previous post. For example: the biceps at the front of the upper arm is bent, and when to contract this muscle bends the facility and forearm and hand move hand shoulder, located muscle triceps behind the humerus and be extensor, and when constrict correct facility and forearm and hand move away from the facility. At the same time the biceps relax so that you can triceps muscle that attracted back to the origin. Sometimes called voluntary muscles; they move involuntarily under conscious control, and skeletal muscles involuntarily moving without conscious control, for example, involuntary movement occurs when a person's hand away from a hot object automatically without thinking about it. Smooth muscle these muscles are smaller than skeletal muscle fibers, and contains a single nucleus. The whereabouts of the smooth muscle walls of the stomach and intestines, bladder and blood vessels. Skeletal muscle; smooth muscle fiber is planned. The way the muscles work smooth working slowly and rhythmically spontaneous contraction followed by relaxation of the normal system, and in this way to move various body processes. Smooth muscle known as involuntary muscles because they are not under the conscious control of the brain. Heart muscle the way the heart muscle when to contract their cells, pushing the blood in the arteries outside the heart, and spins the blood everywhere in the body, bringing food to Khalaaa.tjma heart muscle between the characteristics of the structural muscle and smooth; so that contain Takttat structural Kaladilat, and contains all the muscle cell attack on one nucleus to contract automatically, such as smooth muscle fibers. What happens when the muscle exercise? * When you raise a person several heavy weights for a short period each day, will grow more muscle; this exercise makes the muscle nuclei increase in the production of threaded thick and thin. * When the person performing light exercise regularly for a long time, such as swimming for thirty minutes more than the muscle fibers in their ability to energy that you need to maintain such a muscular effort production. Sometimes it happens naturally confusing to work the muscles; the person feels sometimes painful muscle strain if he exercises uphill for a long time. Cramp structural muscles include muscle contraction spastic, no one knows why it happens like this cramps accurately? It is likely to be the cause or increase too much shortage of the fluid surrounding the salts muscle fibers. Using the proper rest and nutrition the body can correct the situation and stop cramps, muscle tension can happen in smooth for the stomach and intestinal muscles, doctors used heat, massage and medication in the treatment of cramps. May cause muscle work hard skeletal muscle rupture; In severe cases continues to tear up to four days, it is likely to be due to muscle and connective tissue damage, and the right workout can the body and muscles adapt muscular hard work, and far less than the risk of tissue damage. Muscle atrophy of muscle disease: This disease attacks the nervous system and the nerves that stimulate the muscles, and this leads to nerve damage, and thus shrink the muscle gradually become weak, for example by motor neuron disease. Poor muscle: it occurs muscle weakness; because the muscle itself is not working as it should, and is characterized by some muscular disorders, structural gradual atrophy of muscles
