영어에서 BLASTULA 의 뜻은 무엇인가요?
포낭
blastos (그리스어 βλαστός (blastos)에서 "새싹"을 의미하는)은 동물의 배아 발달의 초기 단계에서 형성된 blastocoele이라고 불리는 내부 유체 충진 공동을 둘러싸고있는 blastomeres라고 불리는 중공의 세포입니다. 배아 발달은 정자가 난자를 비옥하게하는 것으로 시작하여 접합체가되어 많은 분열을 일으켜 세포를 공포 (morula)라고 부른다. 낭포가 형성되었을 때만 초기 배아가 배변이됩니다. 포배는 배아가 형성되는 생배기가 형성되는 생배기의 형성을 앞선다. 척추 동물의 포배 (blastula)의 일반적인 특징은 그것이 포배를 둘러싸는 포배 (blastoderm)라고 알려진 파편의 층으로 구성되어 있다는 것입니다. 포유류에서는 포 배를 배반포 (blastocyst)라고합니다. 배반포는 태아의 결정적인 구조를 궁극적으로 일으키는 배아 모체 (또는 내부 세포 덩어리)와 영양 배아 조직을 형성하는 영양 모세포를 포함합니다.
영어 사전에서 blastula 의 정의
사전에있는 포낭의 정의는 중도에서 발생하는 동물 배아의 초기 형태로, 중앙 구멍이있는 세포 구체 (blastosphere)라고도합니다.

Blastula. The cells of the morula form a hollow sphere, the blastula. The cavity of
the blastula is the blastocoel. The blastula possesses an animal and a vegetal
pole. The animal pole of the sea urchin blastula is characterized by a tuft of cilia.
The blastula stage normally is reached as the embryo enters the uterus. The
endoderm is responsible for the gill arches found in the early embryonic states of
vertebrates. In fish, these develop into respiratory organs. In land vertebrates,
they ...

Pattern Formation in Zebrafish
2 Mid-Blastula Transition and the Beginning of Cell Motility The earliest cell
rearrangements in the zebrafish blastula are the simple result of cell divisions. In
the cleavage-stage embryo, cells divide synchronously and rapidly, every 15min.
