Dwarfism results from the under-secretion of which hormone during childhood?
AInsulin from pancreas islets
BThyroxine from thyroid gland
CGrowth hormone from pituitary
DAdrenaline from adrenal medulla
Answer & Solution
Correct answer: C. Growth hormone from pituitary
1. Body height is regulated mainly by **growth hormone** from the pituitary.
2. If the pituitary makes too little growth hormone in childhood, growth slows.
3. The resulting short stature is called **dwarfism**.
4. Too little insulin causes diabetes; too little thyroxine causes cretinism (a different syndrome).
