Answer

Option E) None of the avove


The sensation of thirst is detected by osmoreceptors receptors in the hypothalamus.

  • Hypothalamus is the thirst center that regulates intake of fluids in the body.
  • Osmoreceptors present in the hypothalamus detect dehydration or fluid volume deficit to stimulate thirst.
  • There receptors also stimulate release of anti-diuretic hormone from posterior pituitary to prevent water loss in urine.


As no option choice is matching with the correct answers, none of the above is correct.
