Definition

- Sự hình thành phôi cầu là một bước quan trọng trong quá trình phát triển phôi thai. (The formation of the blastosphere is a crucial step in embryonic development.)
- Các nhà khoa học đang nghiên cứu cấu trúc của phôi cầu. (Scientists are studying the structure of the blastocyst.)
Advanced Usage
- This term is highly specialized and used almost exclusively in academic, medical, and biological contexts related to embryology and developmental biology.
Variants and Related Words
- Phôi nang: A more modern and commonly used Vietnamese term for "blastocyst," especially in human embryology.
- Túi phôi: Another synonymous term meaning "embryonic sac."
Synonyms
- Blastocyst
- Blastosphere
Notes
- "Phôi cầu" is a direct translation of the biological term "blastosphere." In contemporary scientific Vietnamese, "phôi nang" is often preferred, particularly when referring to the mammalian (including human) blastocyst stage. The term is not used in everyday language.
