| 释义 | Graafian follicle noun[ C ] anatomy specialized(alsograafian follicle)uk /ˈɡrɑː.fi.ən ˌfɒl.ɪ.kəl/ us /ˈɡrɑː.fi.ən ˌfɑː.lɪ.kəl/ a small sac(= bag) filled with liquid in the ovary of a human or other mammal that contains a developing egg : During about fourteen days, one of the Graafian follicles that enclose the eggs enlarges and matures, secreting the hormone folliculinestrin. This group of female mice showed retarded follicular development, and their ovaries contained lower numbers of graafian follicles. In one's life, less than 1% of follicles in the ovaries typically develop into the Graafian follicles that could release mature oocytes. This has changed our view of physiological events occurring within the maturing Graafian follicle and fallopian tubes. Peri-ovulatory endocrine activity reflects the numbers of mature Graafian follicles and thus the numbers of oocytes to be shed.
