To draw: The cross-section of a myofibril structure at M line. Introduction: The sacromere is the fundamental unit of the striated muscle tissue. Sacromere is present repeatedly between the two Z-lines. Skeletal muscles are made of the cylindrical cells called myofibres or myocytes. Myofibres possess a number of myofibrils, which are made up of the reiterating unit of the sacromeres. A sacromere contains a long filament which is composed of fibrous protein.
