Uterine contractions are stimulated by

Question

Quizplus · Accepted Answer

Uterine contractions during labor are mainly stimulated by the release of two hormones, oxytocin and prostaglandins. Oxytocin is produced by the hypothalamus and released by the pituitary gland, while prostaglandins are produced by the uterus itself. Relaxin is a hormone that helps to soften and relax the cervix during labor, but it does not directly stimulate uterine contractions. Lochia and lanugo are substances that are expelled from the body after delivery, but they do not play a role in stimulating uterine contractions. Allantois and HCG are substances that are involved in embryonic development, but they do not play a role in labor and delivery.
