(N/A) The foetal ejection reflex is a neuroendocrine mechanism triggered by the fully developed foetus and the placenta.
It involves the following steps:
$1$. Signals originating from the fully developed foetus and the placenta induce mild uterine contractions.
$2$. These contractions trigger the release of the hormone $Oxytocin$ from the maternal posterior pituitary gland.
$3$. $Oxytocin$ acts on the uterine muscles,causing stronger uterine contractions.
$4$. This creates a positive feedback loop where the stimulatory reflex between the uterine contraction and $Oxytocin$ secretion continues,resulting in increasingly stronger contractions.
$5$. This process ultimately leads to the expulsion of the baby out of the uterus through the birth canal,a process known as $Parturition$.
