To add: Neurotransmitter and ATP in the concept map. Introduction: A sliding filament model describes that muscle contracts when thin filaments slide between thick filaments and for this, actin and myosin must touch. The physical connection between the two types of filaments is the “head” portion of each myosin molecule that forms a cross-bridge when it contacts an actin molecule.
