Question

A pregnant female delivers a baby who suffers from stunted growth, mental retardation, low intelligence quotient and abnormal skin. This is the result of?

• A. Cancer of the thyroid gland
• B. Over secretion of pars distalis
• C. Deficiency of iodine in diet
• D. Low secretion of growth hormone

Answer 1

The correct option is C Deficiency of iodine in diet

C. Deficiency of iodine in the diet

Reason: Hypothyroidism during pregnancy causes defective development and maturation of the growing foetus leading to stunted growth. It is caused by the deficiency of iodine in a regular diet. Low secretion of GH caused stunted growth resulting in pituitary dwarfism.

Pars distalis or anterior pituitary Produces Growth Hormone, prolactin (PRL), Thyroid-stimulating hormone (TSH), Adrenocorticotrophic Hormone (ACTH), Lutenising Hormone (LH), and Follicle Stimulating Hormone (FSH).
