The long threadlike cells which help animals move their
bodies are called muscle cells. Muscle cells are types of cells found in muscle
tissues. They are also known as muscle fiber or myocyte. They come in different
specialized forms with various characteristics and properties. Each of the muscle
fiber contains myofibrils or very long chains of contractile units of cell
(sarcomeres). It
is the skeletal muscle fibers that help
support and move the body of the animals and
tend to have peripheral nuclei.
