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.
Best Answer: The appearance of striations in skeletal muscle is caused by the arrangement of the contractile units called sarcomeres that make up the myofibrils inside muscle cells. They are arranged in parallel rows and when all the end (Z-lines) line up next to each other, it creates the striations. Source(s):
