NEET 2018, Biology Q42: Endocrine Glands and Hormones

NEET2018Paper 2018Biology
Q.

Which of the following hormones can play a significant role in osteoporosis?

  1. A

    Aldosterone and Prolactin

  2. B

    Progesterone and Aldosterone

  3. C

    Parathyroid hormone and Prolactin

  4. D

    Estrogen and Parathyroid hormone

Solution

Estrogen promotes the activity of osteoblast and inhibits osteoclast. In an ageing female osteoporosis occurs due to deficiency of estrogen. Parathormone promotes mobilisation of calcium from bone into blood.

Excessive activity of parathormone causes demineralisation leading to osteoporosis.
