- oxytocin
- relaxin
Oxytocin (birth)
- released by
- stimulated by (2)

- released by
posterior pituitary - stimulated by
uterine contraction / cervical stretch
prostaglandin
effect
- uterine contraction
Prostaglandin
- released by
- stimulated by (1)
- effect
- released by
placenta - stimulated by
uterine contraction - effect

- effects (3)
- released by
placenta - stimulated during
uterine contraction
(P) rapidly drops - effects (2)
loosen the ligaments holding the pelvis bone together
loosen vagina and cervix
what are the 2 hormones that cause uterine contraction
- prostaglandin
- oxytocin
what initiates birth
uterine contraction, when (P) rapidly drops
when does the amount of oxytocin rapidly increase
when (P) rapidly decreased of near birthing
what dilates as the uterine contracts
cervix
what directly and indirectly cause uterine contraction
oxytocin
- directly
uterine contractions - indirectly
through prostaglandin
what prepares body during when uterine contraction becomes more frequent
relaxin and oxytocin
what are the hormones released by placenta
P and E
prostaglandin
relaxin
when is prolactin produced
AFTER birth
why is prolactin not produced during pregnancy
high levels of P and E stops anterior pituitary from releasing proactin
lactation
the production and release of milk
hormones involve in lactation
oxytocin and prolactin
