Myocyte A myocyte (also known as a muscle cell) is the type of cell found in muscle tissue.Myocytes are long, tubular cells that develop from myoblasts to form muscles in a process known as myogenesis.ardiomyocytes are the muscle fibres that form the chambers of the heart, and have a single central nucleus. Skeletal muscle fibers help support and move the body and tend to have peripheral nuclei. Smooth muscle cells control involuntary movements such as the peristalsis contractions in the oesophagus and stomach.
