Which of the following statement is wrong ?
Sella turcica is a bony cavity where the pituitary gland is located
Parathyroid hormone decreases the Ca2+ levels in blood
Thymosins play a major role in T cell differentiation
The middle layer of adrenal cortex is zona fasciculata
The middle layer of adrenal cortex is zona fasciculata
B.
Parathyroid hormone decreases the Ca2+ levels in blood
Parathyroid hormone or parathormone is released by parathyroid glands. It regulates the calcium and phosphate balance between blood and other tissues. It increases calcium reabsorption in nephron, mobilises the release of calcium into blood from bones and hence increases blood calcium level.
