Definition of myofilament
WebMyofilament definition, a threadlike filament of actin or myosin that is a component of a myofibril. See more. WebJul 7, 2024 · Myofibrils are essential polymers that are fibrous and long, which consist of two different types of proteins that stack on each other including myosin and actin. Myosin is thick with a globular head, whereas actin is a thin filament and the action between the actin and myosin myofilament leads to muscle contraction. Structure of Sarcomere

Webmyofilament: [ mi″o-fil´ah-ment ] any of the ultramicroscopic threadlike structures composing the myofibrils of striated muscle fibers . Myofilaments are the three protein filaments of myofibrils in muscle cells. The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein. The myofilaments act together in muscle contraction, and in order of size are a thick one of mostly myosin, a thin one of mostly actin, and a very thin one of mostly titin.
