Bundles of myofibrils in a muscle. From Damjanov, 2000.my·o·fi·bril (mī'ō-fī'bril), One of the fine longitudinal fibrils occurring in a skeletal or cardiac muscle fiber comprising many regularly overlapped ultramicroscopic thick and thin myofilaments. Synonym(s): muscular fibril, myofibrilla [myo- + Mod. L. fibrilla, fibril] myofibril (mī′ə-fī′brəl, -fĭb′rəl)n. Any of the threadlike fibrils that make up the contractile part of a striated muscle fiber and are made up chiefly of actin and myosin filaments.myofibril A bundle of contractile fibres within muscle cells.my·o·fi·bril (mī'ō-fī'bril) One of the fine longitudinal fibrils occurring in a skeletal or cardiac muscle fiber and consisting of many regularly overlapped ultramicroscopic thick and thin myofilaments. [myo- + Mod. L. fibrilla, fibril]myofibril a microscopic contractile filament of STRIATED MUSCLE, made up of a series of SARCOMERES. The myofibril is made up of numerous longitudinal filaments of two forms, thick (MYOSIN) and thin (ACTIN). See MUSCLE, I-BAND. Relatively little is known of the contraction of smooth muscle, where contractile elements’ are thought to contain both actin and myosin.myofibrilenUK
