Molecular characterization of an aquaporin cDNA from brain: candidate osmoreceptor and regulator of water balance.
Recently, aquaporin 4 has also been identified in the ADH-secreting neurons of the supraoptic and paraventricular nuclei in the hypothalamus that functions as a hypothalamic osmoreceptor and regulates body water balance.
Vanilloid receptor-related osmotically activated channel (VR-OAC), a candidate vertebrate osmoreceptor.
Increased fluid intake "did not reverse the low subcutaneous oxygen, perhaps because of chronic underhydration and osmoreceptor reset," she said.
An increase in vascular osmolarity triggers the release of antidiuretic hormone (ADH) from the posterior pituitary, primarily in response to osmoreceptor activation in the hypothalamus (McCance & Huether, 2002).
Within the hypothalamus, osmoreceptor cells sense changes in ECF osmolality.
Old age is also thought to be accompanied by increased osmoreceptor sensitivity [3].
Type 2: Defective osmoreceptor DI the increased plasma osmolarity fails to release stored ADH
With advancing age, osmoreceptor sensitivity appears to be maintained [1, 2] or to increase [3], whereas AVP release in response to standing appears to decline [4].
When it reaches 295 mOsm/kg, osmosis of water out of the osmoreceptor cell causes the cell to shrink.
