Question

In human adult females, oxytocin
  1. is secreted by anterior pituitary              
  2. stimulates growth of mammary glands   
  3. stimulates pituitary to secrete vasopressin         
  4. causes strong uterine contractions during parturition


Solution

The correct option is D causes strong uterine contractions during parturition

Oxytocin (child birth hormone), secreted by neurohypophysis of pituitary gland, stimulates contraction of uterus muscles, including labour pain for child birth, when secretion of progesterone hormone declines, making the end of pregnancy. As the sensory impulse of increasing labour pain reaches hypothalamus, more and more oxytocin is released from posterior pituitary under a positive feedback regulation.
