Document Summary
Haploid male or female germ cell that will unite with another of the opposite sex to form a. Zygote ( chromosomes: spermatogonia in men, oocyte in women. Gonad : organ that produces gametes: testes in men, ovaries in women. Changes in female"s oocytes and ovarian follicles: oogenesis production of female gametes, folliculogenesis growth and development of ovarian follicles. Starts with oogonia (formed during fetal development mitosis) Forms primary oocytes in the fetal ovary that stay arrested in prophase i, resumes at beginning of puberty and then until menopause will natural degeneration of the germ cells over time. Primary oocyte starts off at 2 million. Oogonia is the intense mitotic acitivty in embrionic ovary. Ovulation (release of an oocyte from the ovary) initiates your period. Just before ovulation hormones trigger resumption of meiosis in primary oocyte. This starts the transition from primary to secondary oocyte. Resulting in a larger daughter cell called the secondary oocyte, which leaves the ovary during ovulation.
