The mammalian skeletal muscle fiber (myofiber) is a peculiar syncytia as it possesses hundreds of nuclei. In a fully matured myofiber, most nuclei are positioned and spaced regularly at the periphery, just below the plasma membrane. 42,43 The spatial organization of these nuclei is not random. Fiber length and size can vary considerably within a given muscle and between different muscles. Therefore, numbers of nuclei can range from 50-1000 per fiber. For instance in B6 mice an FDB fiber ...Cardiac muscle cells usually have only one, sometimes two, centrally located nuclei and are branched. They also are connected to each other via gap junctions.
