Question:
Identify the incorrect statement among the following
Identify the incorrect statement among the following
Show Hint
Parathyroid hormone raises blood calcium levels—remember "PTH = Pulls The calcium High".
Updated On: May 9, 2025
- Sella turcica is a bony cavity in which pituitary gland is located.
- Parathyroid hormone decreases the $Ca^{+2}$ levels in blood.
- Thymosin plays a major role in T-cell differentiation.
- The middle zone of adrenal cortex is zona fasciculata.
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Parathyroid hormone (PTH) actually increases calcium levels in the blood by stimulating bone resorption, increasing calcium reabsorption in kidneys, and promoting activation of vitamin D for calcium absorption in the intestine.
Thus, statement (2) is incorrect. All other statements are correct: the pituitary sits in the sella turcica, thymosin aids T-cell maturation, and zona fasciculata is the middle adrenal cortex layer.
Thus, statement (2) is incorrect. All other statements are correct: the pituitary sits in the sella turcica, thymosin aids T-cell maturation, and zona fasciculata is the middle adrenal cortex layer.
