As the chief cell type of the heart, cardiac cells are primarily involved in the contractile function of the heart that enables the pumping of blood around the body. Sarcoplasmic reticulum is very abundant in skeletal muscle cells and is closely associated with the myofibrils (and, therefore, the myofilaments). Do muscle cells have a nucleus?
