平滑肌细胞是机体内分布广泛功能重要的细胞类型之一 ,由于其形态单一、构型简单 ,所以长期以来在科研及教学中一直未列入关注重点。近年来多项观察中相继发现 ,随所在器官不同 ,平滑肌细胞的超微结构也有相应的不同 ,因此认为进一步了解其共性及异性实有必要 ,并做如下报道。 Smooth muscle cells are one of the most widely distributed cell types in the body. Because of their single morphology and simple configuration, they have not been included in the research and teaching for a long time. In recent years a number of observations have been found, with the different organs, the ultrastructure of smooth muscle cells are also different accordingly, so that further understanding of its common and heterosexual real need, and do the following report.
