WebMay 21, 2024 · Gleitfilamenttheorie (sliding filament theory), 1954 von HUXLEY entwickelte Theorie der Muskelkontraktion, wonach das Sarkomer als funktionelle Grundeinheit des Muskels aus Aktin– und Myosinfilamenten besteht, die durch ein aufeinander folgendes Greifen der Querbrücken ineinander gleiten ohne ihre Länge zu … WebApr 12, 2024 · The concentric muscle contraction, or concentric phase, is described by the cross-bridge (sliding filament) theory. According to this theory, the myosin heads cyclically attach to specific sites on actin filaments, forming cross-bridges. Each cross-bridging cycle consumes one molecule of adenosine triphosphate, or ATP (energy).

WebAug 13, 2024 · The sliding filament theory of muscle contraction was developed to fit the differences observed in the named bands on the sarcomere at different degrees of muscle contraction and relaxation. The mechanism of contraction is the binding of myosin to actin, forming cross-bridges that generate filament movement (Figure 6.7). Figure 6.7. WebThe sliding filament theory explains the mechanism of muscle contraction based on muscle proteins that slide past each other to generate movement.

These contain even smaller structures called actin and myosin filaments. These filaments slide in and out between each other to form a muscle contraction hence called the sliding filament theory! The diagram above shows part of a myofibril called a sarcomere.
