Question

Hypersecretion of Growth Hormone in adults does not cause further increase in height, because

  • Growth Hormone becomes inactive in adults

  • Epiphyseal plates close after adolescence

  • Bones loose their sensitivity to Growth Hormone in adults

  • Muscle fibres do not grow in size after birth

Answer

B.

Epiphyseal plates close after adolescence

Epiphyseal plate is responsible for the growth of bone which close after adolescence so hypersecretion of growth hormone in adults does not cause further increase in height.
