What do you mean by muscular system of human body. Explain the structural classification?
Answers
Hii!!
The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
On the basis of structure ,it has three types
️Skeletal muscle is also known as voluntary muscle because we can consciously, or voluntarily, control it in response to input by nerve cells. Skeletal muscle, along with cardiac muscle, is also referred to as striated ("striped") .
️Cardiac muscle is only found in the heart, and although it is striated like skeletal muscle, it functions involuntarily. Cardiac and most smooth muscles are autorhythmic-they are capable of contracting spontaneously without nervous or hormonal stimulation.
️Smooth muscle is widely distributed throughout the body, being found in the walls of hollow organs such as our digestive, reproductive, and urinary tracts.Smooth muscle is involuntary-not under our conscious control.
