Nissl Stain (what does it stain?) stains the Nissl bodies, also known as the rough endoplasmic reticulum. Nissl Stain (what does it show us?) - distinguishes neurons and glia from one another. - can be used to identify shape and size of the cell soma (body), not the processes (axons and dendrites). (the simple stain shows the organization of the spinal cord) Brainpower 0:00 / 0:00 Nissl Stain (what does is facilitate the study of?) facilitates the study of cytoarchitecture ...
