Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: Spermatogonia
Concept:

Spermatogenesis begins in the outermost layer of the seminiferous tubules with undifferentiated germ cells.

Solution:

  • The germinal epithelium of the testis is lined with diploid stem cells.


  • These stem cells undergo repeated mitotic divisions to produce spermatogonia (singular: spermatogonium) at an early stage.


  • These spermatogonia will eventually grow into primary spermatocytes.


Why other options are incorrect:

Secondary spermatocytes and spermatids are formed much later via meiosis. Interstitial cells (Leydig cells) are located outside the seminiferous tubules and do not develop from the germinal epithelium; they are responsible for producing testosterone.

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.
