The basic unit of muscular contraction; the sarcomere.
actin and myosin are myofillaments that make up myofibrils (part of a muscle fibre) (so therefore : muscle is an actin or myosin containing structure
myofilament
Actin and myosin
Actin Filaments
Myosin and Actin
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.
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)
Myosin makes up the THICK filaments, and actin makes up the thin filaments of myofibrils.
Actin and myosin are proteins. Protein is a broad category of molecules.
Myosin and actin
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.
