tinh bào
Definition
- Noun (Biology):
- Spermatocyte: A male germ cell that undergoes meiosis to form spermatids, which later develop into spermatozoa (sperm cells). It is a specific stage in the process of spermatogenesis.
Usage Examples
- Noun:
- Tinh bào là một giai đoạn quan trọng trong quá trình sinh tinh. (The spermatocyte is an important stage in the process of spermatogenesis.)
- Các tinh bào phân chia thông qua giảm phân. (Spermatocytes divide through meiosis.)
Advanced Usage
"Tinh bào cấp I" (Primary Spermatocyte): A diploid cell that undergoes the first meiotic division.
- Tinh bào cấp I bắt đầu quá trình giảm phân I. (The primary spermatocyte begins the process of meiosis I.)
"Tinh bào cấp II" (Secondary Spermatocyte): A haploid cell resulting from the first meiotic division, which quickly undergoes the second meiotic division.
- Tinh bào cấp II hình thành từ tinh bào cấp I. (Secondary spermatocytes are formed from primary spermatocytes.)
Variants and Related Words
Sinh tinh (n): Spermatogenesis; the entire process of sperm production.
- Sinh tinh xảy ra trong tinh hoàn. (Spermatogenesis occurs in the testes.)
Tinh trùng (n): Spermatozoon; the mature, motile male sex cell.
- Tinh trùng có khả năng di chuyển để thụ tinh. (Sperm have the ability to move for fertilization.)
Tinh nguyên bào (n): Spermatogonium; a stem cell that gives rise to spermatocytes.
Synonyms
- Male gametocyte: A general term for a cell that develops into gametes; in males, this includes spermatocytes.
- Germ cell: A cell that gives rise to gametes.
Notes on Usage
- Academic Context: The term "tinh bào" is highly specialized and is used almost exclusively in scientific, medical, and biological contexts, particularly when discussing cell biology, anatomy, and reproductive physiology.
- Common Confusion: It should not be confused with "tinh bột" (starch) or "tinh trùng" (sperm). "Tinh bào" refers specifically to a precursor cell in the developmental pathway to becoming sperm.
