Human muscular structure, the muscles of the physical body that employment the skeleton, that are under voluntary control, which are concerned with movement, posture, and balance. Broadly considered, human muscle—like the muscles of all vertebrates—is often divided into skeletal muscle (or skeletal muscle), smooth muscle, and heart muscle. Smooth muscle is under involuntary control and is found within the walls of blood vessels and of structures like the bladder, the intestines, and therefore the stomach. Cardiac muscle makes up the mass of the guts and is liable for the rhythmic contractions of that vital pumping organ; it too is under involuntary control. With only a few exceptions, the arrangement of smooth muscle and heart muscle in humans is just like the arrangement found in other vertebrate animals.

The muscular system is liable for the movement of the physical body. Attached to the bones of the skeleton are about 700 named muscles that structure roughly half a person’s weight. Each of those muscles may be a discrete organ constructed of striated muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is additionally found inside the guts, digestive organs, and blood vessels. In these organs, muscles serve to maneuver substances throughout the body.
