Композиція та гісто-ультраструктурна будова прямого м’яза стегна в нормі

The information on histometric and electron microscopic study of the muscle fibers of the rats’ rectus femoris in the norm is presented. The basic types of muscle fibers and their composition are described. The composition reflects the close morphological interdependence of the structure of myoneural junctions and elements of muscular tissue. It may determine different patterns of both reactive and destructive processes in the skeletal muscles.
