Its Hormone

·         This gland secretes a hormone called parathormone hormone.

Action of this Hormone

·         Low level of calcium ions in the blood stimulate this gland to secretes the parathormone in excess.

·         If blood calcium ions level is high then secretion of this hormone is inhibited.

Under Activity of this Hormone

·         Blood calcium level is decreased down due to its less secretion.

·         As a result, muscular tetany occurs.

Over Activity of Hormone

·         Due to its excess secretion, deficiency of minerals occurs in bones.

·         Cause a kidney stone.
