blastulas

blastulas的音标是["blɑːstrəʊləz] ，基本翻译是囊胚，速记技巧是：“囊”可以理解为“包”和“笼”，即把胚胎像装东西一样装起来，笼统地表示胚胎学上的囊胚。

Blastula这个词来源于希腊语blstula，意为“球形物”。它的变化形式包括名词的复数blastulae和过去式、过去分词的blastulized。相关单词包括：

1. Blastocyst（胚泡）：指的是在卵子受精后，早期胚胎发育的阶段，即囊胚之前的一个阶段。

2. Blastogenesis（胚原细胞增生）：指的是胚胎发育过程中，胚原细胞的增生。

3. Blastomere（滋养层细胞）：指的是囊胚中的细胞，通常用于胚胎移植或体外培养。

4. Blastoderm（内胚层细胞）：指的是早期胚胎发育中形成的内胚层细胞。

5. Blastopore（胚孔）: 指的是早期胚胎发育中，囊胚孔的位置。

6. Blastocystic（胚泡状的）：用来描述类似于胚泡的形状或状态。

7. Blastodermic（内胚层状的）：用来描述具有内胚层细胞特征的物质或结构。

8. Blastocystoid（囊胚样的）：用来描述类似于囊胚的状态或形状。

9. Blastomere separation（滋养层细胞分离）：指的是将囊胚中的滋养层细胞和内细胞团分离的过程，用于体外培养或胚胎移植。

10. Blastocyst-stage（囊胚期）：用来描述胚胎发育过程中的一个特定阶段，即囊胚阶段的时期。这个阶段是胚胎发育的关键阶段之一，涉及到大量的细胞分裂和分化。

常用短语：

1. blastodermization

2. blastoderm fragmentation

3. blastoderm transplantation

4. blastoderm cell division

5. blastoderm cell differentiation

6. blastoderm cell migration

7. blastoderm cell fusion

例句：

1. The fertilized egg underwent blastodermization and began to form distinct tissue layers.

2. The blastoderm fragmentation caused the embryo to be unable to develop properly.

3. The transplanted blastoderm cells quickly began to divide and differentiate into new tissues.

4. The blastoderm cell division was rapid and precise, ensuring the proper development of the embryo.

5. The blastoderm cell migration was crucial for the formation of the nervous system.

Blastoderm Cells: The Foundation of Life

Blastoderm cells are the fundamental building blocks of life, providing the foundation for the development of an organism. Through their division, differentiation, and fusion, blastoderm cells play a crucial role in the formation of tissues, organs, and even entire body plans.

From fertilized eggs to early embryos, blastoderm cells undergo complex processes of division and differentiation to form distinct tissue layers, which then develop into organs and body parts. Blastoderm cell fusion, a rare but crucial event, can result in the formation of new organisms with unique characteristics, further demonstrating the versatility of these fundamental cells.

Blastoderm cells are the driving force behind life"s development, and without them, life as we know it would not exist. Understanding their role in development is essential for understanding life itself, and continues to fascinate biologists and scientists today.
