Question

Oxytocin regulates both uterine contractions and milk production in females.

• A. True
• B. False

Answer 1

The correct option is A

True

Oxytocin stimulates the milk-ejection reflex so that contraction of the smooth muscles around the mammary glands and ducts causes milk to be ejected from the ducts through the nipple. During suckling, sensory receptors in the nipples send impulses to the hypothalamus, which triggers the release of oxytocin. Oxytocin is also
needed to stimulate uterine contractions in women during childbirth.
