中心粒复合体位于植入窝中，由近端中心粒和基体两部分组成。

The centriolar complex was inside implantation fossa and consisted of proximal centriole and basal body .

微管还用于建造中心粒，基体，纤毛和鞭毛。

Microtubules are also used in the construction of centrioles , basal bodies , cilia and flagella .

中段包括5或6个线粒体，一对中心粒及一些泡状结构。

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

中心粒复合体位于核后植入窝中。袖套一侧肥厚，一侧狭窄。

The centriolar complex was in the implantation fossa which was at the posterior end of the nucleus .

中心粒：由两个互成直角的圆筒状小体构成的细胞器。

Centriole A cell organelle consisting of two short tubular structures orientated at right angles to each other .

中段较短，近端中心粒和远端中心粒互相垂直。

The midpiece of spermatozoon is short . The proximal centriole and distal centriole are perpendicular to each other .

鞭毛形成，鞭毛排列鞭毛在生物体上的排列微管还用于建造中心粒，基体，纤毛和鞭毛。

The flagellar arrangement on an organism . Microtubules are also used in the construction of centrioles , basal bodies , cilia and flagella .

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。

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

近端中心粒由两个半圆形中心粒单体相对组成一个空心球体，空心处有一核样致密物质；

Two single hemi global centrioles are opposite to each other , thus constituting the proximal centriole , an empty globe , which is nucleus dense .

该基因过度表达可引起中心粒异常、染色体不稳定和肿瘤形成，在人类多种恶性肿瘤的发生发展过程中起到了至关重要的作用。

Aberrant expression of Aurora kinases may lead to cancer . It plays an important role in the genesis and development of many human malignant tumors .

但中心粒对于纺锤体的形成并不是必须的，尽管具有相似的结构-基体，中心粒对于波动足微管的形成有重要作用。

However , the centriole is not essential for spindle formation , although an analogous structure , the basal body , is responsible for organizing the microtubules of UNDULIPODLA .

在透射电镜下观察到有细胞核膜消失，染色质变成粗颗粒状.中心粒一分为二，两中心粒之间还有纺锤丝牵引；

Under electron microscope , it was found that in some cells the nuclear membrane disappeared partly , chromatin became broadly granular and two centrioles were jointed by spindle fibers .

远端中心粒呈钟罩形，顶端与近端中心粒相连，底部开口处与精子尾部轴丝端相连。

The distal centriole is like a bell , with its top connecting to the proximal centriole and with the entrance of its bottom connecting to the axoneme of the sperm tail .

随着精细胞的发育，生毛体结构变得松散，亚单位分化形成的中心粒彼此分开扩散到外围，中心为无定形物质。

In the process of sperm cell development , the blepharoplast became loose , and the centrioles originated from the subunits separated from each other and dispersed towards the surface , with the amorphous material in the center .
