text: Skeletal muscle fibers are, however, unique among muscles in at least two important respects: (1) they are multinucleate cells, formed during development by the end-to-end fusion of mononuclear myoblasts (Stockdale and Holtzer, 1961) and (2) they are directly innervated by motoneurons whose cell bodies and dendrites are located in the central nervous system, either brain stem or spinal cord (Kernell, 2006).
