Normal Skeletal Muscle - Gomori Trichrome

This is a sample of normal muscle prepared with the Gomori Trichrome stain. The muscle fibers appear a bluish green. Note that normal muscle fibers have a polygonal shape to them, and are not exceptionally rounded. Note also that the muscle fibers tend to be about the same size. The nuclei (which appear dark) are located laterally, near the cell membrane. There are small white cracks in each muscle fiber - these are an artifact caused during preparation of the sample. Another common artifact (not shown) is patches of bright red staining secondary to partial fixation of the muscle due to exposure to formalin fumes.
