Definition of myofibril. : any of the longitudinal parallel contractile elements of a muscle cell that are composed of myosin and actin.
Sliding filament model of muscle contraction. A myofibril (also known as a muscle fibril) is a basic rod-like unit of a muscle cell. Muscles are composed of tubular cells called myocytes, known as muscle fibers in striated muscle, and these cells in turn contain many chains of myofibrils. Thin filaments consist primarily of the protein actin, coiled with nebulin filaments. 2  Actin, when polymerized into filaments, forms the ladder along which the myosin filaments climb to generate motion. 3  Thick filaments consist primarily of the protein myosin, held in place by titin filaments.
