Vedclass · Answer

(D) Osmoreceptors are specialized sensory neurons located in the hypothalamus that monitor the osmotic pressure of the blood.They are activated by changes in blood volume,body fluid volume,and excessive ionic concentration (osmolarity).Excessive loss of water from the body (e.g.,due to sweating or dehydration) leads to an increase in blood osmolarity and a decrease in blood volume.Since all these factors trigger the osmoreceptors to stimulate the release of $ADH$ (Antidiuretic Hormone) from the neurohypophysis,the correct answer is $D$.
