- Skeletal muscle cells are often called striated muscle cells due to the banded appearance.
- They consist of bundles of fibres. Each fibre is one long, multi-nucleated cell and is made up of bundle of fibrils.
- These fibrils are divided into thick and thin filament sections called striations. The thick appear as dark bands, and the thin appear as light bands.
- Each repeating unit of dark and light bands in a myofibril is called a sarcomere.
