Oogonia
degeneration of oogonia
atresia

Contain oocytes (egg cells) in various stages of development
Ovarian Follicles
releases an oocyte
each month during ovulation
Mature Graafian Follicle
Single layer of squamous cells
around the oocyte
Primordial follicle
Layers of cuboidal granulosa
cells around the oocyte
Primary follicle
Antral cavity forms
Secondary follicle
Follicle mature
ready to ovulate
oocyte
Graafian follicle
Follicle ruptures
releasing oocyte
Ovulation
What are the stages of follicular development in order
Primordial Follicle, Primary Follicle, Secondary Follicle, Graafian Follicle, Ovulation
completes the
preparation of uterine lining
Progesterone
work with
progesterone
Estrogens
relaxes uterine muscles
and pubic symphysis
Relaxin
decreases secretion of FSH and LH
Inhibin
