Which of these is not an important component of initiation of parturition in humans?
1 Increase in estrogen and progesterone ratio
2 Synthesis of prostaglandins
3 Release of oxytocin
4 Release of prolactin

Under the influence of oxytocin which layer of the uterus exhibits strong contractions during parturition?
1 Endometrium
2 Myometrium
3 Perimetrium
4 Both (1) and (3)
Explanation:
Oxytocin acts on the endometrium of the uterus causing the contraction of the myometrium resulting in delivery of the foetus.

During pregnancy, which part of uterus helps in expansion and then in contraction during child birth
1 Perimetrium
2 Myometrium
3 Endometrium
4 None of these
Explanation:
Deep to the perimetrium layer, the myometrium forms the middle muscular layer of the uterus. During pregnancy the myometrium allows the uterus to expand and then contracts the uterus during childbirth.

In human adult females oxytocin
1 Stimulates pituitary to secrete vasopressin
2 Causes strong uterine contractions during parturition
3 Is secreted by anterior pituitary
4 Stimulates growth of mammary glands
Explanation:
Oxytocin acts on the uterine muscles and causes stronger uterine contractions, which in turn stimulates further secretion of oxytocin during parturition..

Foetal ejection reflex in human female is induced by
1 Differentiation of mammary glands
2 Pressure exerted by amniotic fluid
3 Release of oxytocin from pituitary
4 Fully developed foetus and placenta
Explanation:
The signals for parturition originate from the fully developed foetus and the placenta which induce mild uterine contractions called foetal ejection reflex.
