The A band
minimal overlap of thin and thick myofilaments.
minimal overlap of thin and thick myofilaments.
Myosin
I Band
thick filaments
The thick myofilaments are formed from a protein called myosin.
the myofilaments themselves do not contract, they slide, this is called the Sliding Filament theory, in which the thick filament (Myosin) slides over the thin filament (Actin).
Sarcomeres contain myofilaments which consist of actin (thin) and Myosin (thick).
No, myofibrils contain both thick filaments (myosin) and thin filaments (actin) which when activated overlap each other as part of muscular contraction.
Myofilaments Two types: actin (thin filament) & myosin (thick filament)
The thin myofilaments are actin. They slide between the thick filaments called myosin.
The myofilaments are actin and myosin.
