Which of the Following Structures Plays a Critical Role in Maintaining

Question

Which of the following structures plays a critical role in maintaining the early pregnancy?
A) corpus albicans
B) primordial follicle
C) corpus luteum
D) corona radiata

Accepted Answer

The corpus luteum is formed from the ruptured follicle after ovulation and plays a critical role in maintaining the early pregnancy by secreting progesterone. Progesterone is necessary to maintain the uterine lining and prevent menstruation, allowing the developing embryo to implant and continue to grow. The other structures listed (corpus albicans, primordial follicle, and corona radiata) do not have a significant role in maintaining early pregnancy.
