Discuss the various roles of oxytocin
What will be an ideal response?
Oxytocin stimulates contraction of uterine smooth muscle to help expel the infant during childbirth, and it promotes ejection of milk from the mammary glands (breasts) during breast-feeding. Appropriately, oxytocin secretion is increased by reflexes that originate within the birth canal during childbirth and by reflexes that are triggered when the infant suckles the breast. In addition to these two major physiologic effects, oxytocin influences a variety of behaviors, especially maternal behaviors. For example, this hormone fittingly facilitates bonding, or attachment, between a mother and her infant. For this reason, oxytocin is sometimes nicknamed the "love hormone" or "cuddle chemical.".
