Its structure is similar to that of a centriole.

The midpiece consists of 5 or 6 mitochondria, a pair of centriole and several vesicles.

中段包括5或6个线粒体，一对中心粒及一些泡状结构。

It has the same structure as the mature parental centriole, but is only about half its length.

The spermatocyte is of polygonal shape, which contains a centriole appendage formed by the chromatoid body's surrounding the centriole.

初级精母细胞多边形，拟染色体包围中心粒形成中心粒附属物；

The disappearing of the centriolar adjunct and proximal centriole in succession might be considered as a sign of being mature completely of the spermatid.

中心粒附属物和近端中心粒的相继消失可以看作是成熟的最后标志。
