The Sliding Filament Mechanism - ️️- A sarcomere goes from z-line to z-line and has thick filaments (myosin) in the middle within the thin filaments (actin) on the sides - During contraction, the thin filaments move inwards over the thick filaments - When this happens, the z-lines move closer together - This occurs simultaneously along the entire fibre and all sarcomeres shorten to the same degree - Neither the length of the thin filaments or thick filaments themselves changes, just th...
