Question

growth hormone hypersecretion
hypersecretion of growth hormone after the epiphyseal plate closes
causes a disorder known as
options: gigantism, acromegaly, growth hormone deficiency, congenital hypothyroidism

Explanation:

To solve this, we recall the effects of growth hormone (GH) hypersecretion:

• Gigantism: Occurs when GH is over-secreted before the epiphyseal plates close (during childhood).
• Acromegaly: Occurs when GH is over-secreted after the epiphyseal plates close (in adulthood).
• Growth hormone deficiency: Is a lack of GH, not hypersecretion.
• Congenital hypothyroidism: Related to thyroid hormone, not GH.

The question specifies hypersecretion after the epiphyseal plate closes, so the correct disorder is acromegaly.

Answer:

B. acromegaly (assuming the options are labeled with letters; if not, the correct option is "acromegaly")
