Answers
Answer =
stages of egg maturation and we can distinguish them are as follows:
1.Oogonium - Meiosis arrest,synthesis RNAs,histones and proteins.
2.primary follicle -formation of follicle,synthesis RNAs,histone,proteins and their storage.
3.Cirtical alveolus stage (Secondary oocyte) - synthesis and release of E2 by granulosa cells stimulated by FSH.starts chemical communication oocyte-follicle cells.
4.Vittellogenic follicle (secondary follicle)-
5.Mature follicle-LH stimulates of follicle cells and synthesis and release of progestagens,progestagens activate meiosis resumption.
6.egg -accumulation of nutrients and genetic material to sustain embryo development until zygotic activation.
