Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Secretory phase
Concept:

The endometrium undergoes cyclic changes to create a highly hospitable environment for a potential embryo.

Solution:

  • After ovulation, the menstrual cycle enters the secretory phase (also known as the luteal phase).


  • During this time, the corpus luteum secretes large amounts of progesterone.


  • Progesterone causes the endometrium to become highly vascularized, thick, and spongy. Endometrial glands secrete glycogen-rich fluids to nourish and prepare for the implantation of a blastocyst.


Why other options are incorrect:

The proliferative phase only rebuilds the lining after menstruation. The menstrual phase involves shedding the lining. Ovulation is simply the release of the egg.
