A myofibril (also known as a muscle fibril or sarcostyle) is a basic rod-like organelle of a muscle cell. Skeletal muscles are composed of long, tubular cells known as muscle fibers, and these cells contain many chains of myofibrils. Each myofibril has a diameter of 1–2 micrometres. They are created during embryonic development in a process known as myogenesis. WebMyotube is A skeletal muscle fiber formed by the fusion of myoblasts during a developmental stage; a few myofibrils occur at the periphery, and the central core is occupied by nuclei and sarcoplasm so that the fiber has a tubular appearance and u have … WebNov 29, 2024 · In vivo, these cells spontaneously generate myotubes and myofibrils.
