Question 4

Besides human chorionic gonadotropin, what other specific thyroid-stimulating hormone is secreted by the placenta during pregnancy?

View answer and explanation
Question 5

From where do the hormones that stimulate increased maternal thyroxine production during pregnancy primarily originate?

View answer and explanation
Question 6

The increased secretion of several hormones, including thyroxine, contributes to an increase in the basal metabolic rate of a pregnant woman. By approximately what percentage does this rate increase?

View answer and explanation
