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.
One commonality between skeletal and cardiac muscle is the presence of striations due to the arrangement of actin and myosin into regular myofibrils. The presence of myofibrils and many mitochondria in cardiac muscle cells provides them with great strength and endurance to pump blood throughout an entire lifetime. Visceral muscle cells are found in the organs, blood vessels, and bronchioles of the body to move substances throughout the body.
