What does blastulae mean?
The blastula is a critical stage in the development of an animal embryo, marking a significant transition from the morula stage. During this stage, the embryo undergoes rapid cell division and differentiation, ultimately giving rise to the gastrula. The blastula is characterized by a fluid-filled cavity surrounded by a layer of cells, which will eventually give rise to the various tissues and organs of the developing organism. This stage is essential for the proper development and formation of the embryo, and any disruptions or abnormalities during this stage can have significant consequences for the developing organism. The blastula is a fundamental concept in embryology and developmental biology, and its study has important implications for our understanding of animal development and the origins of life.
noun
A blastula is an early stage in the development of an animal embryo, characterized by a fluid-filled cavity surrounded by a layer of cells. This stage typically occurs after the morula stage and before the gastrula stage.
- 1. An early stage in the development of an animal embryo, characterized by a fluid-filled cavity surrounded by a layer of cells.
"During embryonic development, the fertilized egg undergoes several stages, including the blastula, before forming a gastrula and eventually a fetus."
"The blastula stage is a critical period in embryonic development, during which the embryo undergoes rapid cell division and differentiation."

Etymology of blastulae
The term 'blastula' comes from the Greek word 'blastos,' meaning 'germ' or 'sprout.' This term was first used in the 19th century to describe the early stages of animal development, and has since become a standard term in embryology and developmental biology.
Usage notes
The term 'blastula' is typically used in formal or technical contexts, such as in scientific research or academic writing. It is not commonly used in everyday conversation or in popular media.
