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. Each fibre is commanded by a nerve which makes it to contract.
