01.There are some muscle fibers here that show atrophy. The number of cells is the same as before the atrophy occurred, but the size of some fibers is reduced. This is a response to injury by "downsizing" to conserve the cell. In this case,innervation of the small fibers in the center was lost. This is a trichrome stain.

01.图示萎缩肌纤维。肌纤维的数目与萎缩前一样，但体积缩小。这是对损伤的反应，通过“缩小”保护细胞。本例，中间的小细胞神经支配消失。这是三色染色法。
