Question 1 of 5
Which of the following hormones is responsible for stimulating uterine contractions during labor?
Correct Answer: D
Rationale: Oxytocin is the correct answer as it is the hormone responsible for stimulating uterine contractions during labor. Oxytocin is produced by the pituitary gland and plays a crucial role in initiating and sustaining labor contractions. It acts on the smooth muscle cells of the uterus, causing them to contract and aiding in the progression of labor. Progesterone and estrogen are involved in preparing the uterus for pregnancy but do not directly stimulate contractions. Prolactin is responsible for milk production, not uterine contractions.
Therefore, D is the correct answer due to its specific role in labor contractions.
