Three-dimensional organization of mammalian skeletal muscle membrane systems.
The three-dimensional arrangement of mitochondria and sarcoplasmic reticulum membrane systems of vertebrate extrafusal and intrafusal muscle fiber types was studied by scanning electron microscopy (SEM) in the specimens prepared by the A-ODO method. SEM observations on specimens treated by HCl-digestion method revealed distinct differences in motor endplates in the different muscle fiber types.
