| 释义 | 〔implant〕To become attached to and embedded in the uterine lining. Used of a fertilized egg.（受精卵）着床：附着或进入子宫壁，用于描述受精卵〔zygote〕The organism that develops from a zygote. 从受精卵发育而成的有机体〔morula〕The spherical embryonic mass of blastomeres formed before the blastula and resulting from cleavage of the fertilized ovum.桑椹胚：形成于囊胚之前且处于胚胎期内的球形裂球群，由受精卵细胞的分裂而成〔trophoblast〕The outermost layer of cells of the blastocyst that attaches the fertilized ovum to the uterine wall and serves as a nutritive pathway for the embryo. Also called trophoderm 胚胎滋养层：囊胚细胞的最外层，它会将受精卵与子宫壁连在一起，同时它是胚胎获取营养的通道 也作 trophoderm〔blastoderm〕The layer of cells formed by the cleavage of a fertilized mammalian egg. It later divides into the three germ layers from which the embryo develops.胚盘：由哺乳动物受精卵分裂而形成的细胞层。后期分裂为三层，胚胎由此发育〔blastula〕An early embryonic form produced by cleavage of a fertilized ovum and consisting of a spherical layer of cells surrounding a fluid-filled cavity. Also called blastosphere 囊胚：由分裂受精卵产生的早期胚胎外形，由围绕充满液体的洞的球形细胞层组成 也作 blastosphere〔embryo〕The fertilized egg of a vertebrate animal following cleavage.胚胎：卵裂后的脊椎动物的受精卵〔cleavage〕The series of mitotic cell divisions that produces a blastula from a fertilized ovum. It is the basis of the multicellularity of complex organisms. Also called segmentation 卵裂，卵割：由一组有丝分裂细胞从受精卵中生成的囊胚，是复杂有机体中多细胞的主要成分 也作 segmentation〔meroblastic〕Undergoing partial cleavage. Used of a fertilized egg.偏裂卵的：部分分裂的。用于指受精卵〔sporozoite〕Any of the minute undeveloped sporozoans produced by multiple fission of a zygote or spore, especially at the stage just before it infects a new host cell.孢子体、子孢子：一种由受精卵或孢子的成熟分裂而产生的微小的未发育的孢子物，尤指在未感染一个新的寄生细胞阶段〔gamete〕A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce the fertilized egg.配子：具有染色体的单倍数的生殖细胞，尤指一个成熟精子或卵子能与相对性的配子结合而产生受精卵〔blastomere〕Any of the cells resulting from the cleavage of a fertilized ovum during early embryonic development.分裂球：在早期胚胎发育时受精卵分裂产生的任何细胞〔conception〕Formation of a viable zygote by the union of the male sperm and the female ovum; fertilization.受精：通过雄性精子与雌性卵细胞结合而形成受精卵的过程；受精〔zoon〕An animal developed from a fertilized egg.动物：由受精卵发育而成的动物〔progesterone〕A steroid hormone, C21H 30O 2, secreted by the corpus luteum of the ovary and by the placenta, that acts to prepare the uterus for implantation of the fertilized ovum, to maintain pregnancy, and to promote development of the mammary glands. 黄体荷尔蒙，黄体酮：类固醇荷尔蒙，化学式为C21H 30O 2，由卵巢的黄体和胎盘分泌，其活动准备子宫移植受精卵子，保持受孕，以及促进乳腺的增大 〔sporogony〕Reproduction by multiple fission of a spore or zygote, characteristic of many sporozoans. Sporogony results in the production of sporozoites.孢子生殖：通过一个孢子或受精卵的扩大分裂而生殖，以众多的孢体为特征。孢子生殖导致孢子的产生〔zygote〕The cell formed by the union of two gametes, especially a fertilized ovum before cleavage. 合子：两个配子结合而成的细胞，特指分裂前的受精卵〔uterus〕A hollow muscular organ located in the pelvic cavity of female mammals in which the fertilized egg implants and develops. Also called womb 子宫：女性哺乳动物体内位于盆腔里的中空的肌肉器官，受精卵可在里面生长发育 也作 womb〔monozygotic〕Derived from a single fertilized ovum or embryonic cell mass. Used especially of identical twins.单卵的：由一个受精卵或胚胎细胞群而派生来的。尤指用于同卵双〔synkaryon〕The nucleus of a fertilized egg immediately after the male and female nuclei have fused.受精核：雄性与雌性胞核溶合后受精卵细胞的细胞核〔fertilization〕The union of male and female gametes to form a zygote.受精卵：雄性和雌性配子的结合形成受精卵 |
