Highly sensitive cells within the hypothalamus that react to changes in blood composition and cause the release of antidiuretic hormone (ADH) when appropriate are called ________.
A) thermoreceptors
B) baroreceptors
C) mechanoreceptors
D) osmoreceptors

Question

Quizplus · Accepted Answer

Osmoreceptors are sensory cells within the hypothalamus that detect changes in blood osmolality, or the concentration of solutes in the blood. When osmolality increases, indicating dehydration, osmoreceptors signal for the release of antidiuretic hormone (ADH) from the posterior pituitary gland, which helps conserve water in the kidneys. Thermoreceptors detect changes in temperature, baroreceptors detect changes in blood pressure, and mechanoreceptors detect mechanical stimuli like pressure and vibration.
