primary nucleus 中文意思是什麼
primary nucleus
解釋
初生核-
The primary cell propagated 8 times and were small fusiform or triangle and smaller than hepatocytes with larger nucleus and less plasma ; it was 88. 2 % in the growing period of 4 ( superscript th ) generation cells and the stains of alb and ck19 were positive in immunocytochemical
所獲得的原代細胞共傳8代，細胞呈小梭形或三角形，體積較小，胞核較大，而胞漿較少；第4代細胞中進入生長期的細胞約佔88 . 2 % ；免疫細胞化學染色顯示細胞胞質中alb 、 ck19染色陽性。 -
The other male gamete fuses with the secondary nucleus, forming the primary endosperm nucleus.
另一個雄配子和次生核結合形成初生胚乳核。 -
The nucleus of the solitary tract ( nts ) innervates the visceral primary afferents of most organs in the neck, chest and abdomen. the rostral part of nts receives the special visceral, gustatory afferents, while the mid - caudal part receives the respiratory, gastrointestinal and cardiovascular afferents
孤束核（ nts ）接受頸、胸和腹腔大部分內臟器官的感覺傳入，其吻段1 / 3主要與特殊內臟感覺的味覺傳入有關，中尾段2 / 3主要與呼吸器官、胃腸道和心血管等內臟傳入有關。 -
During the stages of primary and secondary spermatogonium, components of the nucleolus, called chromatoid bodies ( cb ), are excluded from the nucleus
精原細胞階段，部分核仁物質外排，成為擬染色質小體，其上聚集一群線粒體，構成「線粒體區」 。 -
One fuses with the egg cell to form a zygote while the other either degenerates or, in certain angiosperms, fuses with the polar nuclei to give the primary endosperm nucleus
一個與卵細胞結合形成受精卵，另一個要麼退化，要麼在某些被子植物中與極核結合形成初生胚乳核。 -
The endosperm is usually triploid and develops from the primary endosperm nucleus, the triploid nucleus resulting from the fusion of one of the male gametes from the pollen tube with the polar nuclei in the embryo sac
胚乳通常是三倍體，由初生胚乳核發育而來，三倍體核來源於花粉管中的雄配子與胚囊中兩個極核的融合。 -
At the beginning, the cytoplasm is evently distributed, then it is polar - distribution and at last it only remains between the apical cap and the sperm nucleus. during the period of spermatogonium, chromatin in the nucleus is in the shape of conglomeration and the nucleus is big ( i. e. the proportion of the nucleus to cytoplasm is bigger than spermatocyte ). at the stage of primary spermatocyte, chromatin accumulates to sc complexity. the nucleus of the mature sperm takes the shape of a plate and filmentous chromatins exist freely in uncondensed nucleus
精子發生過程中，細胞器由少到多，到最後解體；細胞質從均勻分佈，到精細胞期極性分佈，最後殘留于成熟精子的頂帽和精核之間；細胞核在精原細胞期，染色質異固縮，胞核大，即核質比大於后續的精母細胞；在初級精母細胞中，染色質凝聚為sc復合體，到成熟精子，精核呈碟狀，染色質呈絲狀游離于非濃縮的核中。
