Muscular System
The
muscular system is answerable for the movement of the body. connected to the bones of the frame area unit regarding 700 named muscles that compose roughly 1/2 a person’s weight. every of those muscles may be a separate organ made of muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is additionally found within the guts, biological process organs, and blood vessels.
Human muscular structure, the muscles of the body that job the frame, that area unit beneath voluntary management, which area unit involved with movement, posture, and balance. loosely thought of, human muscle—like the muscles of all vertebrates—is usually divided into musculus (or skeletal muscle), sleek muscle, and heart muscle. sleek muscle is beneath involuntary management and is found within the walls of blood vessels and of structures like the bladder, the intestines, and also the abdomen. heart muscle makes up the mass of the guts and is answerable for the sapphic contractions of that important pumping organ; it too is beneath involuntary management. With only a few exceptions, the arrangement of sleek muscle and heart muscle in humans is similar to the arrangement found in alternative vertebrate animals.
This article worries with the skeletal muscles of the body, with
stress on muscle movements and also the changes that have occurred in human skeletal muscle system as a results of the long method|biological process} process that concerned the belief of upright posture. sleek muscle and heart muscle and also the
physiology of contraction area unit treated at nice length within the article muscle. For descriptions of disorders that have an effect on the human muscular structure, see muscle unwellness
