alleryOversecretion of growth hormone during childhood, leading to abnormal overgrowth and increased height, results in:
AGigantism
BAcromegaly
CDwarfism
DCretinism
Answer & Solution
Correct answer: A. Gigantism
1. Growth hormone (GH) controls the growth of muscles, cartilage and long bones.
2. Excess GH in children causes overgrowth of all body tissues and abnormal height, called gigantism.
3. Decreased GH in children causes dwarfism, so that is wrong.
4. Excess GH in adults causes acromegaly, and cretinism is due to thyroid hormone deficiency, so both are ruled out.
