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.
Looking at one muscle fiber, you will see that almost the entire cross section of the muscle fiber is taken up by long, cylindrical strands of contractile proteins called myofibrils. Typically there are hundreds of these in one cross section of a muscle fiber.ooking at one myofibril, we see that it is divided into segments called sarcomeres. These are the contractile units of a muscle. A dark stripe called a Z disc marks the ends of one sarcomere and the beginning of the next. Sarcomeres are composed of thick filaments and thin filaments.
