Definitions for "Sliding filament theory"
The sliding filament theory explains how muscles contract by postulating the interaction of actin and myosin macromolecules inside muscle cells.
Concept that within the myofibrils, actin and myosin filaments slide across each other, thus inducing shortening. Fundamental mechanism underlying contraction of muscle.
A proposed mechanism of muscle contraction based on formation and breaking of crossbridges between actin and myosin filaments, causing them to slide together.
