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.
Because the striations on adjacent myofibrils are usually aligned, the entire muscle fiber appears uniformly striated. 1  In each sarcomere, the broad band which appears dark in standard histological procedures is called the A-band. 2  The broad light band between the dark bands is the I-band.
