Sliding Filament Theory
Contraction of a muscle fibre takes place by the sliding of the thin filaments over the thick filaments.
This theory explains how muscles contract by the sliding of actin (thin) filaments over myosin (thick) filaments.
Terms:
Actin
Thin filament involved in muscle contraction
Myosin
Thick filament involved in muscle contraction
The sliding filament theory describes the process of muscle contraction, where actin and myosin filaments slide past each other, shortening the sarcomere and causing contraction.
Common Use:
Understanding muscle contraction mechanisms.
