Question

Dwarfism occurs due to

• A. Excess secretion of thyroxine
• B. Less secretion of growth hormone
• C. Less secretion of adrenaline
• D. Excess secretion of growth hormone

Answer 1

The correct option is B Less secretion of growth hormone

• Growth hormone(GH) is secreted by the anterior pituitary gland.
• Over-secretion of GH stimulates abnormal growth of the body leading to gigantism and low secretion of GH results in stunted growth resulting in dwarfism.
• Symptoms include Shortened arms and legs, A short neck, Broad, rounded chest, Slightly flattened cheekbones, slow growth pattern and unusually small stature (below average height).
• Hence Dwarfism occurs due to less secretion of growth hormone.
• So, the correct answer is 'Less secretion of growth hormone'.
