This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Physiology
All of the following development events are dependent on the production of maternal or fetal glucocoicoid, EXCEPT: 
Select and explain. 
A. Induction of thymic involution, B. Production of surfactant by type II alveolar cells, C. Functional thyroid, D. Functional hypothalamopituitary axis
C: Functional thyroid
Answer: C: Functional thyroid 
Explanation: Functions of maternal / fetal coicosteroids in the fetus include Synthesis of surfactant in the lungs, induction of thymic involution, proper development of hypo-thalamo-pituitary axis. Development of functional thyroid is not found to be dependant on the maternal or fetal glucocoicoids. Ref: Ganong's Review of Medical Physiology, 25th Edition, Pages 373-75.
