Question

The hormone which is not involved in maintaining $C{a}^{2+}$ balance in the human body includes ________.

• A. Cortisol
• B. Aldosterone
• C. Parathormone
• D. Thyrocalcitonin

Answer 1

The correct option is A Cortisol

• The thyroid secretes thyrocalcitonin when there is a high calcium level in the blood. It lowers the calcium level by suppressing calcium ions released from the bone.
• Aldosterone is a steroid hormone secreted by the adrenal cortex which regulates the sodium level in the body. Aldosterone also enhances renal calcium reabsorption.
• Parathormone is secreted by the parathyroid gland, it regulates the calcium and phosphate balance between the blood and tissue.
• Cortisol secreted by the adrenal cortex is a stress hormone and also shows an anti-insulin effect.

Hence, the correct answer is option A - i.e., Cortisol.
