Reproductive System Flashcards
Anterior Pituitary Hormones
FSH/LH
FSH
Follicular Stimulating Hormone, estrogen synthesis, Sertoli (sperm)
LH
Lutenizing Hormone, Triggers ovulation, Leydig (testosterone)
Sertoli Cell
Sperm production, inhibin production
Leydig Cell
Testosterone
GnRH
Hypothalamus
Negative Estradiol Feedback
Follicular/Luteal Phases
Positive Estradiol Feedback
Ovulation
Negative Progesterone Feedback
Luteal Phase
The Primary Oocyte is arrested in what phase and when?
Prophase I, Birth
When does the secondary oocyte form?
Puberty
Secondary Oocyte + Sperm
Zygote
Estrogens
Fat deposit, ovary maturation, mammary glands (ovary origin)
Androgens
hair growth, libido (ovary origin)
Chorion
gas exchange
Amnion
encloses amniotic fluid
Amniotic Fluid
Protects against mechanical shock and desiccation
Yolk Sac
Encloses yolk
Yolk
gas exchange, immune system, nutrition, blood cell formation
Allantois
Acts as a kidney and helps with gas exchange
What phase of meiosis II does the secondary oocyte stop?
Metaphase II
Follicular Phase
LH and FSH stimulate several follicles to grow
Ovulation
LH and FSH stimulate maturation of one of the growing follicles
Luteal Phase
LH stimulates growth of a corpus lute from follicular tissue left behind after ovulation
