Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Integrating cell cycle kinetics (G0 arrest) with histological secretion mechanisms.
Students often memorize that sebaceous glands are holocrine but fail to deduce the physiological consequence: 'whole-cell shedding' makes the gland entirely dependent on continuous mitotic turnover, unlike merocrine glands which preserve cellular integrity.
