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.
The two contractile proteins in myofibrils are actin (part of the thin filament) and myosin (part of the thick filament). The regulatory proteins troponin and tropomysium, which are also part of the... Skeletal muscles are composed of many individual cells known as muscle fibers. Each individual muscle fiber is in turn composed of a number of smaller myofibrils. Three types of proteins form myofibrils: contractile, regulatory, and structural. Contractile proteins generate force for muscle contraction.
