Question

Thick skin, long arms and legs are due to hypersecretion of hormone from

• A. Thyroid
• B. Thymus
• C. Anterior pituitary
• D. Posterior pituitary

Answer 1

Answer: (C)

Anterior pituitary

Thick skin, long arms and legs are the features of acromegaly, a disorder caused due to hypersecretion of growth hormone (GH) in adults. GH is secreted from anterior lobe of pituitary gland. Hypersecretion of GH results in abnormal thickening of bones and soft tissues as well.

• Thyroid gland secretes thyroxine hormone which increases oxygen consumption by metabolically active tissues.
• Thymus gland secretes thymosin hormone which plays an important role in the differentiation of T-lymphocytes.
• Posterior pituitary secretes oxytocin which aids in childbirth and vasopressin hormone which increases water reabsorption in kidneys.

So, the correct answer is 'Anterior pituitary'.
