Propolis Cognitive Error Autopsy

Official Correct Choice:
Option B: Posterior pituitary gland
Concept: Endocrine origin and release of ADH.

Solution: ADH (vasopressin) is synthesized by neurosecretory cells in the hypothalamus and stored/released from the posterior pituitary gland (neurohypophysis).

Why other options are incorrect:
  • Option A: The adrenal cortex secretes mineralocorticoids like aldosterone.

  • Option C: The thyroid gland secretes thyroxine and calcitonin.

  • Option D: The renal cortex synthesizes hormones like erythropoietin and renin.

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.
