It is a contractile protein :)
The thick filament is composed of the myosin molecule. The thin filament is composed of the actin molecule. Flexing the head of myosin provides the powerstroke.
Sarcomeres are composed of actin (thin filaments) and myosin (thick filaments).
Thick Filaments
Myosin and actin
Spindle fibers are composed of a protein called myosin and originate from a cell organelle called the centriole
The thick filament is composed of the myosin molecule. The thin filament is composed of the actin molecule. Flexing the head of myosin provides the powerstroke.
Myosin
Actin. Myosin are the thin ones.... it's actually the reverseThe thin filaments are composed primarily by the protein Actin.The thick filaments are composed primarily of the protein Myosin.
Sarcomeres are composed of actin (thin filaments) and myosin (thick filaments).
Actin and myosin are proteins. Protein is a broad category of molecules.

Most myosin molecules are composed of both a head and a tail domain.
