Under secretion of thyroxine/hypothyroidism in children causes

• A. Cretinism
• B. Dwarfism
• C. Goitre
• D. Acromegaly
  

Answer 1

Answer: (A)

Cretinism

A. Cretinism is the retarded mental and physical development in children due to hyposecretion of thyroid hormones in children.

B. Dwarfism occurs due to hyposecretion of growth hormone during the period of skeletal growth.

C. Goitre is the enlargement of thyroid gland which occurs due to deficiency of iodine in the body. Iodine is needed for the synthesis of thyroid hormone. When the iodine levels are low, thyroid gland becomes hyper active and enlarged to compensate the deficiency of thyroid hormone in the body. The enlarged thyroid gland is visible as a swelling in the throat known as goitre.

D. Acromegaly occurs due to hypersecretion of growth hormone in adulthood due to which bones become abnormally thick.

So, the correct answer is 'Cretinism'.
