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. WebDec 5, 2012 · It has also been suggested that the formation of myotubes may activate intrinsic nerve regeneration and formation of the neuromuscular junction [23,27,28].
