Praxis 5857 Practice Test Practice Question
Which of the following hormones is responsible for development and maintenance of the uterine lining during pregnancy?
Correct Answer: B
Rationale: Progesterone plays a crucial role in the development and maintenance of the uterine lining, preparing it for implantation and supporting early pregnancy. It ensures that the endometrium remains thick and nutrient-rich for the developing embryo.
Estrogen, while important for regulating the menstrual cycle and supporting pregnancy, primarily works in conjunction with progesterone rather than independently maintaining the uterine lining. Testosterone is primarily a male hormone and does not have a direct role in uterine lining maintenance. Human Chorionic Gonadotropin (hCG) is vital for signaling pregnancy but does not directly maintain the uterine lining; rather, it helps sustain progesterone production in early pregnancy.
