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.
There are two other types. One is smooth muscle, which has no visible striations and it also involuntary. This is found in arteries and the walls of the digestive, urinary, other hollow organs and respiratory tracts and the irises of the eye.
