Figure 3: Photomicrograph (Case 5) showing well-preserved architecture with no significant replacement by fibrofatty tissue or internalization of nuclei. Photomicrograph (A) there is predominance of type II fibers with peripheral accumulation of reaction product in some (solid arrow). Type I fibers are comparatively smaller in size and at places seen in groups (dotted arrow) (B) NADH, X200, (C) NADH, ×400
