Question

Gland responsible for calcium metabolism is

• A. Thymus
• B. Thyroid
• C. Parathyroid
• D. Adrenal

Answer 1

The correct option is C Parathyroid

A. Thymus gland is associated with the development of immune system and present on the dorsal side of heart. It secretes thymosin hormone which plays an important role in the differentiation of T-lymphocytes.

B. Thyroid gland is situated between the trachea and larynx in the neck and secretes thyroxine hormone which increases oxygen consumption by metabolically active tissues.

C. Parathyroid gland is present in the form of four small pouches which are embedded in the posterior surface of lobes of thyroid gland. This gland secretes parathormone which increases calcium reabsorption from the bones and causes mobilisation of calcium in the blood.

D. Adrenal gland is present on upper side of kidneys and has two parts, adrenal cortex which secrete glucocorticoids, mineralocorticoids and sexocorticoids and adrenal medulla which secrete adrenaline and nor-adrenaline hormone.

Hence, the gland responsible for calcium metabolism is parathyroid gland.

So, the correct answer is 'Parathyroid'.
