Vedclass · Answer

(A) The process of parturition is induced by a complex neuroendocrine mechanism.$1$. The signals for parturition originate from the fully developed foetus and the placenta,which induce mild uterine contractions called the foetal ejection reflex.$2$. This triggers the release of oxytocin from the maternal pituitary,which acts on the uterine muscle and causes stronger uterine contractions.$3$. Additionally,the placenta secretes corticotrophin-releasing hormone $(CRH)$,which acts as a 'placental clock' to determine the length of gestation and the timing of birth.Since both statements are scientifically accurate and the $CRH$ mechanism is part of the overall hormonal control of parturition,the Assertion and Reason are both correct.

$A$: Corticotrophin-releasing hormone is a part of the clock that establishes the timing of birth.
$R$: The signals for parturition originate from the fully developed foetus and placenta,which induce mild uterine contractions called the foetal ejection reflex.
