A myofibril (also known as a muscle fibril or sarcostyle) is a basic rod-like organelle of a muscle cell. Skeletal muscles are composed of long, tubular cells known as muscle fibers, and these cells contain many chains of myofibrils. Each myofibril has a diameter of 1–2 micrometres. They are created during embryonic development in a process known as myogenesis.
WebMyofibrils contain subunits called sarcomere made up of precise arrangements of actin and myosin filaments. Sarcomere are attached end to end throughout the length of the myofibril, and their junction points are called Z-lines. Attached to the Z-lines are strands of actin and two accessory proteins that form the thin filaments.
