WebJul 22, 2024 · In order to understand what the sliding filament theory of muscle contraction is, we must start with myofibrils. Myofibrils are smaller than a human hair, which means that the actin & myosin filaments are even smaller than this. In order to trigger the sliding filament process, the body needs to activate the muscle through the nervous system.
