Muscles

Within a large muscle there are different layers. What are those layers and how do they allow the muscle to work?

It defines of the muscle and the layers of the muscle are very small and it gets biiger. In the muscle it can grow up to be big or small.

The layers from smallest to biggest are myofilaments, myofibril, muscle cell, fasicle, and then finally whole muscle. Muscles are stronger due to these multiple layers just like the twisted steel cords used in bridges and other large construction projects.

The layers start with the whole muscle and then break down into the fasicle, the muscle cell, the myofibril, and then finally the myofilaments. These different layers create a stronger muscle. The layers are twisted together which makes it stronger.
