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.
Their major function is to give strength to the body and support it; they also produce movements. There are three major categories of muscles; Skeletal muscles Cardiac muscles, and Smooth muscles. These muscles are made up of muscular fibers. Muscle fibers are of two kinds: striated muscle fibers and non-striated muscle fibers. Muscles that contain striated muscle fibers are called striated muscle and muscles that contain non-striated muscle fibers are called non-striated muscles. The difference between striated and non-striated muscles is that in striated muscles, the contractile fibrils are aligned parallel, and their regions form stripes that are easily visible under a microscope, whereas non-striated muscles do not have stripes on them, they give a poor appearance under the microscope.
