An individual muscle fiber may also be called a myofiber or a muscle cell. Each
muscle fiber is a single, narrow cell that spans the entire length of a muscle.
The multiple nuclei arise from the fact that each muscle fiber develops from the
fusion of many cells (called myoblasts). ... Anything that lowers the level of
myostatin also leads to an increase in fiber size.
