Follicogenesis

What is the correct order of follicle development

primordial follicle → primary → secondary → tertiary → preovulatory → ovulation

which follicle stage is an antral follicle

tertiary follicle is also known as antral follicle

what is the difference between pre-antral and antral follicles?

antral follicles are gonadotropic DEPENDENT where pre-antral follicles are gonadotropic INDEPENDENT

what are distinguishable features in a primordial cell?

cells contain a flattened layer of granulosa cells

what are distinguishable features of a primary cell

flatten granulosa cells become cubiodal, multiple layers of granulosa cells are beginning formation

what are distinguishable features of a secondary cell

granulosa cells continue to multiply

zona pellucida begins to form around centered oocyte

theca interna and externa are beginning formation around granulosa cells

what are distinguishable features of a tertiary (antral) cell

antral cavity (fluid filled space) begins to seperate the oocyte and granulosa cells

Antrum is dependent on gonadotropinswhat are distinguishable features of a

what is a germ line cyst

a germ line cyst is a cluster of germ cells

what holds germ-line cysts together, and what is the purpose

cytoplasmic bridges are holding germ cell cluster together. The bidge will allow for an exchange of cell content (RNA, organelles, etc.)

what is the product of a germ line cyst and what are the steps of the process

germ line cysts will undergo meiosis

germ line cysts will arrested in prophase 1 until maturity/ovulation

germ cell cluster all begin to form pre-granulosa cells

one germ cell will be more developed than the other and go onto to a primordial follicle while the rest of the cells undergo atresia

what hormone is produced by granulosa cells

estradiol
