Question

unless foetal ejection reflex is produced,normal parturition does not occur substantiate the statement

Answer 1

Parturition- the process of delivery of the foetus, is induced by a complex neuro-endocrine mechanism. The first step initiating this mechanism is the foetal-ejection reflex, therefore normal parturition does not occur unless foetal-ejection reflex is not produced.
Process of parturition :

• The signals of parturition originate from fully-developed foetus and placenta which induces mild uterine contractions known as foetal-ejection reflex.
• These contractions results in release of maternal hormone oxytocin from pituitary gland.
• Oxytocin promotes further contraction of uterine muscles.
• These contractions stimulate secretion of more oxytocin.
• The synergistic combination of uterine contraction and oxytocin secretion results in stronger contractions.
• This finally leads to the explusion of baby out of the uterus through birth canal that is vagina.
