Rating Newest Oldest. Best Answer: The muscles are made up of packages of stretchable fibre like material. 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.

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. The number of fibres, contracting, determine the strength of muscles work. Muscle is mainly composed of muscle cells. Within the cells are myofibrils; myofibrils contain sarcomeres, which are composed of actin and myosin.
