Collips hormone is secreted by
Thyroid
Pineal
Thymus
Parathyroid
Parathyroid Gland & Its Disorders -
The chief cells of the parathyroid secrete a hormone called parathyroid hormone (PTH) or parathormone or also called Collip’s hormone.
This hormone regulates the calcium and phosphate balance between the blood and other tissues.
It mobilises the release of calcium into the blood from the bones.
PTH increases calcium absorption from the intestines.
It increases calcium resorption from the nephrons (and inhibits phosphate reabsorption) of the kidneys.
Parathyroids are under the feeding back control of blood calcium level.
A fall in blood calcium stimulates them to secrete parathormone, a rise in blood calcium inhibits parathormone secretion from them.
Thus PTH has an effect that opposes the effect of calcitonin.
Hence, the correct option is parathyroid
