Question 90

which two hormones are essential to initiate labor in humans

Answer 90

Question 91

which hormone is responsible for milk production? milk ejection?

Answer 91

Question 92

Labor is an example of a positive feedback mechanism. What does that mean?

Answer 92

The response to the stimulus enhances the stimulus. The more a baby descends into the pelvis and stretches the uterus, the more oxytocin is produced and the stronger the contractions become.
