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.
The transverse striations of skeletal muscle form a characteristic pattern of light and dark bands within which are narrower bands. These bands are dependent upon the arrangement of the two sets of sliding filaments and the connections between them.he combination of a motor nerve and the group of muscle fibers that it innervates is called the motor unit. Each branch of a motor nerve in a motor unit extends to a separate muscle fiber. All the muscle fibers that constitute such a unit contract almost simultaneously when they are excited.
