Striations are a key attribute to identify skeletal and cardiac muscle types. Although striations are usually visible in most sections of these muscle types, it can sometimes take a little adjustment of the microscope lighting to see them clearly.
The A and I bands repeat along the length of the muscle fibers to create the striations visible under the light microscope. 1  Sarcomeres repeat along skeletal and cardiac fibers. 2  Components between adjacent Z-lines comprise the sarcomere. 3  Sarcomeres are considered the functional units of striated muscles.n views of this muscle type, striations are not as strong as those of skeletal muscle. Other structural features are usually apparent and of use for identification if the striations are weak. Due to constant activity cardiac muscle has a constant need for oxygen and glucose delivery.
