Describe the bands that create the light and dark areas of skeletal muscle fibers known as striations
What will be an ideal response?
I bands and A bands create the light and dark areas known as striations on a skeletal muscle fiber. I bands, or light bands, contain only thin filaments. These bands are lighter because they allow more light to pass through. A bands, or dark bands, contain thick filaments. The thick filaments block more light than the thin filaments.
