Every fibre of the muscle is approximately forty millimeter in length and is made up of a number of very small strands which are known as fibrils. These fibres are extremely slender, so much so that one square centimeter of a muscle contains in it up to one million fibres.
However, the three main muscles that make up the muscular system are the skeletal, smooth and cardiac muscles. The skeletal muscle is mainly responsible for movement. Each physical function consciously performed by a person, such as speaking and walking, requires the skeletal muscle.
