Q

Ovaries

A

Synthesize and secrete estrogen and progesterone (regulated by LH and FSH)

17
Q

Estrogen

A

Female maturation

18
Q

Progesterone

A

Secreted by the corpus luteum during the luteal phase, stimulates the development and maintenance of the endometrium for implantation

19
Q

Menstrual Cycle

A

Follicular Phase, Ovulation, Luteal Phase, Menstruation

20
Q

Follicular Phase

A

Growth of the follicle, decrease in progesterone, increasing GnRH and FSH

21
Q

Ovulation

A

Follicle bursts, releases ovum into the fallopian tubes, surge of LH, peak estrogen levels

22
Q

Luteal Phase

A

High LH levels began to drop, degradation of the corpus luteum, triggering menstruation

23
Q

Menstruation

A

Corpus lutes atrophies due to decreased LH, drop in progesterone and estrogen levels

24
Q

Corona Radiata

A

First barrier that the sperm must penetrate

25
Q

Cortical Reaction

A

Calcium ions are released into the cytoplasm, formation of the fertilization membrane
