blastulas的音標是["blɑ?str??l?z] ，基本翻譯是囊胚，速記技巧是：“囊”可以理解為“包”和“籠”，即把胚胎像裝東西一樣裝起來，籠統地表示胚胎學上的囊胚。

Blastula這個詞來源于希臘語blstula，意為“球形物”。它的變化形式包括名詞的復數blastulae和過去式、過去分詞的blastulized。相關單詞包括：

1. Blastocyst（胚泡）：指的是在卵子受精后，早期胚胎發育的階段，即囊胚之前的一個階段。

2. Blastogenesis（胚原細胞增生）：指的是胚胎發育過程中，胚原細胞的增生。

3. Blastomere（滋養層細胞）：指的是囊胚中的細胞，通常用于胚胎移植或體外培養。

4. Blastoderm（內胚層細胞）：指的是早期胚胎發育中形成的內胚層細胞。

5. Blastopore（胚孔）: 指的是早期胚胎發育中，囊胚孔的位置。

6. Blastocystic（胚泡狀的）：用來描述類似于胚泡的形狀或狀態。

7. Blastodermic（內胚層狀的）：用來描述具有內胚層細胞特征的物質或結構。

8. Blastocystoid（囊胚樣的）：用來描述類似于囊胚的狀態或形狀。

9. Blastomere separation（滋養層細胞分離）：指的是將囊胚中的滋養層細胞和內細胞團分離的過程，用于體外培養或胚胎移植。

10. Blastocyst-stage（囊胚期）：用來描述胚胎發育過程中的一個特定階段，即囊胚階段的時期。這個階段是胚胎發育的關鍵階段之一，涉及到大量的細胞分裂和分化。

常用短語：

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.

6. The blastoderm cell fusion resulted in the formation of a new organism with unique characteristics.

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.
