GENERAL HISTOLOGY

Detailed explanation-1: -An osmoreceptor is a sensory receptor primarily found in the hypothalamus of most homeothermic organisms that detects changes in osmotic pressure.

Detailed explanation-2: -An osmoreceptor is a sensory receptor, primarily found in the hypothalamus of most homeothermic organisms, that detects changes in osmotic pressure. Osmoreceptors detect changes in plasma osmolarity (ie. concentration of solutes dissolved in the blood).

Detailed explanation-3: -Osmoreceptors in the hypothalamus sense changes in the osmotic pressure of blood. When the osmotic pressure of blood changes, either more dilute or more concentrated, water diffusion into and out of the osmoreceptor cells occurs.

Detailed explanation-4: -Osmoreceptors maintain the osmolality of the blood through a coordinated set of neuroendocrine, autonomic, and behavioral feedbacks. These responses aid cellular function by maintaining the osmolar gradient of various ions.
