Sliding Filament Theory: Steps for Muscle Contraction

WebA sarcomere is the basic contractile unit of a myocyte (muscle fibre). A sarcomere is composed of two main protein filaments (thin actin and thick myosin filaments) which are the active structures responsible for muscular contraction. The widely accepted theory describing muscular contraction is called the sliding filament theory, which proposes that … WebThis same concept is used in the Sliding Filament theory, only on a microscopic level. Within each sarcomere, centrally located myosin or thick filaments are stretched between the opposing fingers or actin filaments extending from each Z disc.
