Causes strong uterine contractions during parturition
Is secreted by anterior pituitary
Stimulates growth of mammary glands
The correct option is B Causes strong uterine contractions during parturition
The posterior lobe of the pituitary gland secretes oxytocin and vasopressin. In the human adult female, oxytocin stimulates contractions of the womb during labor. The hormone stimulates the uterine muscles to contract, so labor begins. It also increases the production of prostaglandins, which move labor along and increases the contractions even more. Once the baby is born, oxytocin promotes lactation by moving the milk into the breast. Once the baby stops feeding, the production of the hormone stops until the next feeding
So, the correct answer is 'Causes strong uterine contractions during parturition'
