Propolis Cognitive Error Autopsy

Official Correct Choice:
Option A: Luteinizing hormone
Concept:

The physical release of the egg requires an acute biochemical trigger mid-cycle.

Solution:

  • The surge of Luteinizing Hormone (LH) from the anterior pituitary directly targets the mature Graafian follicle in the ovary.


  • It induces proteolytic enzymes that digest the follicle wall, resulting in the rupture and release of the secondary oocyte into the fallopian tube (oviduct). This process is ovulation.


Why other options are incorrect:

FSH develops the follicle. Estrogen thickens the uterus. Progesterone maintains the uterus post-ovulation. Only LH is the acute trigger for the actual ovulatory event.

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
