Hypothalamus

Vedclass · Answer

(A) Osmoreceptors are specialized sensory neurons located in the $Hypothalamus$ of the brain.These receptors are highly sensitive to changes in blood osmolarity.When there is an increase in blood osmolarity (e.g.,due to dehydration),osmoreceptors are activated.This activation stimulates the $Hypothalamus$ to release $Antidiuretic$ $Hormone$ $(ADH)$ or $Vasopressin$ from the neurohypophysis,which promotes water reabsorption in the kidneys to maintain fluid balance.
