The striations that are evident in skeletal muscle are due to the areas between the sacromeres that is referred to as the Z-lines.keletal Muscle (as well as Cardiac Muscle) have striations do to their sarcomere's anatomy. The sarcomere is the functional unit of the muscle and appears striated because th â¦ e different thick and thin filaments present.
Each skeletal muscle cell is made up of many precursor cells, called myoblasts, which have fused together to form one long, thin cell with many nuclei. (To see illustrations and more detailed descriptions of muscle cells, visit this page.) Thats HOW a muscle cell syncytium is made. Now lets think about WHY.
