Which one of the following four glands is correctly matched with the accompanying description?

  1. A
    Thyroid - hyperactivity in young children causes cretinism
  2. B
    Thymus - starts undergoing atrophy after puberty
  3. C
    Parathyroid - secretes parathormone which promotes movement of calcium ions from blood into bones during calcification
  4. D
    Pancreas - Delta cells of the Islets of Langerhans secrete a hormone which stimulates glycolysis in liver.

Solution & Step-by-step Explanation

The thymus gland is large at birth but starts shrinking (atrophy) after puberty and is eventually replaced by fat in old age.Hypoactivity (not hyperactivity) of the thyroid causes cretinism.Parathormone increases blood calcium by mobilizing it from bones (resorption), not moving it into bones.Pancreatic alpha cells secrete glucagon, which stimulates glycogenolysis, not glycolysis.
