The body's muscle system is composed of skeletal muscle, smooth muscle and myocardium organ system. However, few people know that in fact the body has at least 639 muscles. The human muscle system is controlled by the nervous system and the brain. The main functions of the human body muscles include: "to help the body movement, help in the body circulation of blood, to the body change posture, but also for the body to provide strength and balance.
In the muscles of many people, the muscles of the eyes are the busiest. The muscles of the eyes are called extraocular muscles. Extracorporeal muscle is small and strong, the efficiency is very high. Because the eyes have six muscles control the rotation of the eye, so that we can see each goal. The six muscles, including four rectus and two oblique, four rectus muscle is: "upper rectus, inferior rectus, medial rectus and lateral rectus." 2 oblique is: "upper oblique and oblique Muscle. "The normal movement of the eye by the six eye muscles together to complete.
Such as looking up, must both sides of the rectus (up) and the lower oblique (upward) at the same time contraction. Side view is the side of the lateral rectus and the other side of the medial rectus at the same time contraction; eyes together as the center line (polymerization), the eyes of the rectus must be contraction at the same time. When we usually brains, the eye will keep turning; when we are absent-minded, the eye will be aimlessly turn. People's inner activities can also be seen from the rotation of the eye. The eye in the direction of rotation, there is always more than one muscle in the main role, the other several muscles from the coordination effect. But when the dominant force of the six muscles as long as there is one or a few inflammation, trauma or neurological disorders, eyes muscle movements are not coordinated.
So the eye muscles are the busiest muscle of mankind. Other busy muscles are heart muscles and diaphragm (breathing) muscles, because they need to work without interruption.
