鲤鱼精子超微结构的研究

鲤鱼精子由头部，中片和尾部组成，头部的细胞核卵形，染色质致密。核中有些小空隙，空中的电子致密物质存在。中片紧连在核的后端。中片由中心粒复合体和袖套组成。中心粒复合体位于核后植入窝中，袖套一侧肥厚，一侧狭窄，袖套中有线粒体和囊泡。囊泡有二类，一类含有电子致密物质；另一类无电子致密物质。近袖套内膜处的细胞质中还存在着与内膜平行的膜，精子尾部从袖套腔中伸出。尾部的轴丝与基体相接。尾部的近核端多有许多囊泡

A STUDY ON THE FINE STRUCTURE OF THE SPERMATOZOON OF TELEOST Cyprinus carpio(LINNAEUS)

The spermatozoon of teleost Cyprnus carpio(Linnaeus)consisted of head, mid-pieceand fail.The nucleus,within which there were some gaps,of the head was allipse.There wereelectron-dense materials in the gaps. The mid-piece, consisting of centriolar complex andsleeve,was connected to the posterior of the nucleus. The centriolar complex was in theimplantation fossa which was at the posterior end of the nucleus.There were mitochondriaand some vesicles in the sleeve.The vesicles were of two types: one contains someelectron-dense materials.the other was electron transparent.The membrane which was parallel to the inner membrane of the sleeve could be seen within the cytoplasm of the sleeve.Thetail was thin and long.It was connected with hasal body and stretches out of the sleeve. Atthe proximal end of the tail therc were many vesicles outside the axoneme.The vesicles wereelectron transparent.The distal end of the tail,however, did not contain any vesicles.
