'' alternate dark and light bands'' mean explain

Answer 1

Heyaaa,,,

The entire muscle show alternate dark and light strips and therefore called stripped muscle. ... They have stripes or light and dark bands.

In between; the A bands is a light area where there are no thick myofilaments, only thin actin filaments. These are called the I Bands. The dark bands are the striations seen with the light microscope. When a muscle contracts the light I bands disappear and the dark A bands move closer together.
