Read following statements (a-d) and choose the option with only correct statements. a. Parturition occurs due to a complex neuroendocrine mechanism at the end of gestation period. b. The signals for parturition originate from fully developed foetus and placenta which induces mild uterine contraction. c. Foetal ejection reflex triggers release of oxytocin from foetal pituitary. d. Oxytocin reduces uterine contraction under positive feedback control and causes expulsion of placenta followed by foetus known as parturition. a and b b and c c and d a and d

A : Corticotrophin releasing hormone is a 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 foetal ejection reflex .

Given below are the steps involved in parturition. Arrange them in proper sequence and select the correct option. I. The induction of mild uterine contractions is called foetal ejection reflex. II. Stronger uterine contractions causing the further release of oxytocin. III. Origination of signals from the fully developed foetus and placenta. IV. Release of oxytocin from maternal pituitary V. Expulsion of baby from the birth canal (a) III , IV , I , II , V (b) III, I , IV , II , V (c) I, III , II , IV ,V (d) II , IV , III, I,V
