Myofibrils account for roughly 80% of cellular volume, and are the contractile elements of the muscle cell. Myofibrils consist of repeating units called sarcomeres (the contractile unit of the myofibril), which have overlapping myofilaments connected to Z discs at either end of the sarcomere.
As we know myofibrils are the contractile units that make up each muscle fibre. Myofibrils can be looked upon as the building blocks of muscle and contain units called sarcomeres. Sarcomeres are the smallest functional unit of skeletal muscle and are composed of two protein filaments; actin and myosin. Actin is a thin filament and myosin is a thick filament, as shown on the following diagram, and it is the interaction between these two filaments that causes a muscle to contract and shorten.
