Muscular System- Myofibril Flashcards Quizlet
WebSkeletal muscle is composed of muscle fibres which have smaller units called myofibrils. There are three types of proteins that make up each myofibril; they are contractile, regulatory and structural proteins. By contractile proteins, we mean actin (thin filament) and myosin (thick filament). Each actin filament is composed of two helical “F ... WebMuscle hypertrophy or muscle building involves a hypertrophy or increase in size of skeletal muscle through a growth in size of its component cells.Two factors contribute to hypertrophy: sarcoplasmic hypertrophy, which focuses more on increased muscle glycogen storage; and myofibrillar hypertrophy, which focuses more on increased myofibril size.
