Actin and myosin are proteins. Protein is a broad category of molecules.
Actin Filaments
myosin and actin
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.
Myosin and actin
The two types of protein that are in your muscle cells are actin and myosin. What they do is they slide past each other and that makes a muscle cell work.
Protein.
Actin and Myosin
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
Thick filaments are made of the protein myosin and thin filaments are made of the protein actin. Myosin and actin filaments are arranged to form and overlapping pattern which gives muscle tissue its striated appearance.
myosin
The two filaments involved are myosin and actin. Actin: is the framework and slides over the myosin filament when the muscle is shortened. myosin: is a thick filament Also a sacromere: is made up of the actin and myosin. It is the functional unit of a muscle fibre and extends from z line to z line. A muscle contraction: is many sacromeres shortening ( actin sliding over myosin)
