Which hormone is primarily responsible for triggering ovulation in the menstrual cycle?
Answer: Luteinizing hormone (LH)
A surge in luteinizing hormone (LH) from the anterior pituitary triggers ovulation around day 14 of a 28-day cycle.
The fertilized egg typically implants in which layer of the uterus?
Answer: Endometrium
The blastocyst implants into the endometrium (decidua) approximately 6–10 days after fertilization.
Which structure connects the fetus to the placenta?
Answer: Umbilical cord
The umbilical cord contains two arteries and one vein that carry blood between the fetus and placenta.
What is the primary function of the corpus luteum after ovulation?
Answer: Produce progesterone to support early pregnancy
The corpus luteum secretes progesterone to maintain the endometrial lining until the placenta takes over at about 10 weeks.
Which phase of the menstrual cycle is characterized by endometrial thickening under estrogen influence?
Answer: Proliferative phase
The proliferative phase occurs after menstruation when rising estrogen causes the endometrium to thicken and regenerate.
The placenta is fully functional and takes over hormone production from the corpus luteum at approximately which gestational week?
Answer: 10 weeks
The luteal-placental shift occurs around 10 weeks of gestation when the placenta assumes progesterone production.
