The human body contains six hundred and thirty-nine muscles, each with its function according to its location of the body, and the most famous functions of the muscles that function the movement, it is responsible for the movement of the human fully, and divide the muscles of the human body in terms of movement to voluntary muscles and muscles involuntary, Which moves the human limbs, but the muscles are voluntary is like the heart muscle working continuously to perform its task, the movement of muscles in the expansion and constriction to make a certain movement each muscle according to its location, you pull the bones related to or removed according to the movement that has been every contraction followed by the spread, It is a Normal mode of muscle. The muscles work according to the law of all or nothingness. When the muscle contractes, all of its parts contract with the same intensity. The level of movement varies according to the intensity of constriction, which affects all parts of the muscle, either simple, medium or severe movement. In order for the muscles to remain in good health to be able to perform their movement, the human diet must be well in addition to taking care of them in terms of performing exercises that maintain muscle strength and effectiveness.
In the human body is also a skeleton that forms the body’s stent and shape, which is the solid part of the body, which contains materials that make it capable of growth, destruction and construction. This structure consists of two parts: a pivotal structure and a lateral structure. The axial axis is the center of the body, The thorax and the thoracic stump, and the terminal structure is the component of the forearms and legs.
As we mentioned earlier, muscle is responsible for human movement by converting energy from chemical to kinetic and makes movement through contact with bones, but the muscles and bones do not connect directly directly, but there is a tool called links tend to resemble cords, tendons extend between the bone and muscle and tendon tendon connected to one bone And the second is the muscle. As for the mechanism of movement, it occurs when the muscle contractions leading to a small size, which in turn leads to pulling the tendon connected to them, which in turn pulls the bone attached to it, but the tendon itself is a tape consisting of connective tissue, connective tissue etc. Composed Balauter’s share of the fiber, and its function is linking with another muscle is part of the body Kaladilat together or associates muscles to bones. It is robust in its composition and is capable of carrying the effort and pressure during human movement for long periods of time, despite its small size in total for the parts that connect them.
