In the sliding filament model, the thick and thin filaments past each other, shortening the sarcomere, i.e., actin and myosin filaments do not shorten, rather actin filaments slide over myosin filaments.
Sliding filament theory can be best explained as:
Held on 30 Apr 2015 · Verified 9 Jul 2026.
When myofilaments slide pass each other actin filaments shorten while myosin filament do not shorten.
Actin and myosin filaments shorten and slide pass each other.
Actin and myosin filaments do not shorten, rather slide pass each other.
When myofilaments slide pass each other, myosin filaments shorten while actin filaments do not shorten.
