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.
Under the microscope, the ends of the blocks appear as lines, making cardiac muscle cells appear to have regularly arranged striations. In the muscle tissue, the cardiac muscle cells are connected in branching networks. Cardiac muscle is innervated by both sympathetic and parasympathetic autonomic motor axons.
