Parturition is induced by a complex neuroendocrine mechanism. (True/false)

Parturition is induced by a complex neuroendocrine mechanism. Explain.

Assertion (A): Parturition is induced by a complex neuro endocrine mechanism. Reason (R ): At the end of gestation period, the maternal pituitary releases prolactin which causes uterine contractions.

(A) : The process of delivery of the foetus is called parturition. (R) : It is induced by a complex neuro-endocrine mechanism.

Read the following sentences about human reproduction: A. The process of childbirth or parturition is induced by a complex neuroendocrine mechanism involving oxytocin. B. The reproductive cycle of all primate mammals is called the menstrual cycle. C. Most of the major organ systems of the foetus including genital organ systems of the foetus including genital organs are developed by the end of 24 weeks. D . The second meiotic division of secondary oocyte is unequal and results in the formation of an ovum and a second polar body. How many from the above is/ are incorrect ?

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

The signals for parturition originate from the fully developed foetus only. (True/false)

Assertion: Parturition is induced by neural signal in maternal pituitary. Reason: At the end of gestation period, the maternal pituitary releases prolactin which causes uterine contractions.
