您要查找的是不是:
- The testis at deteriorated phase reduces in volume, and is translucent, and the mature sperms in seminiferous tubule have almost been extruded. 退化期:精巢体积减小,半透明乳白色,生精小管内的成熟精子几乎排空。
- It appeared that seasonal changes in seminiferous tubule diameter and epithelial height were in accordance with testis weight. 曲细精管直径和生精上皮高度与睾丸重的季节性变化相一致。
- The testis at spermatid phase develops continually, and is deep in color, and the spermatogenetic cells in seminiferous tubule are primarily composed of spermatids. 精细胞期,精巢体积继续增大,颜色加深,生精小管内的生殖细胞以精细胞为主;
- The testis at mature sperm phase get to the biggest in volume, and is purple, and the spermatogenetic cells in seminiferous tubule are almost composed of mature sperms. 成熟精子期,精巢体积可达最大,紫红色,生精小管内充满着成熟的精子;
- Spermaries comprise many seminiferous tubules. 精巢由许多精小管组成;
- The testis at spermatocyte phase develops, and is translucent, and the spermatogenetic cells in seminiferous tubule are primarily composed of primary spermatocytes and secondary spermatocytes. 精母细胞期:精巢体积增大,半透明乳白色,主要由处于初级精母细胞和次级精母细胞阶段的生殖细胞组成;
- Spermatogenesis is a complex and very efficient process that begins with the division and differentiation of the spermatogenic stem cell within the seminiferous tubule of the testis. 精子发生是一个复杂的过程,涉及到由精原细胞转化为初级精母细胞的有丝分裂过程,又经历了从初级精母细胞形成精子细胞的减数分裂过程,最后精子细胞经过变态形成精子。
- The results demonstrated that the testis tissue construction of the Polycelis planarians was very analogous with one of seminiferous tubule of testis of mammalia, but some differences still existed. 结果表明:在光学显微镜下,多目涡虫精巢的组织结构与哺乳类睾丸中曲细精管的结构类似,但也有一些差别。
- Seminiferous tubule failure in adult 成人生精管功能衰竭
- cross section area of seminiferous tubule 曲细精管横截面积
- puberal seminiferous tubule failure 青春期曲细精管衰竭
- seminiferous tubule microinjection 曲细精管注射法
- The length each stage of the cycle of semi-niferous epithelium occupies on the seminiferous tubule, was determined by continual paraffin sections of the seminiferous tubules. 3.应用精细管的连续石蜡切片测定了小白鼠生精上皮周期各期在精细管上所占的长度,并观察了它们在精细管上的排列顺序。
- Basement membrane of seminiferous tubule 生精小管基底膜
- The sperm originate in gonial cells (spermatogonia) in the walls of seminiferous tubules. 精子产生于输精管壁的性母细胞(精原细胞)。
- Longitudinal section of a testicle showing the seminiferous tubules and the convoluted epididymis. 睾丸纵切面,示生精小管和迂回蟠曲的附睾。
- From days 14 to 35, Tyro 3 appeared on Sertoli cell processes toward adluminal compartment of seminiferous tubules. 在生后2到5周,Tyro 3主要定位在Sertoli细胞近腔室包绕生殖细胞的突起上;
- The development of the male germ cells in different seminiferous tubules was different. 不同精小管内生殖细胞的发育是不同步的。
- Conclusions In interstitial tissue tissue encircled of the individual seminiferous tubules and have spaces. 淋巴管存在于纵隔内,小叶内未见典型淋巴管。
- Inside these tubes (called seminiferous tubules) the process of sperm production (called spermatogenesis) takes place. 在这些管道(称为生精小管)里,是精子产生(称为精子发生)的场所。
