Receptor example sentences

Hormone receptors present on the cell membrane of the target cells are called membrane-bound receptors and the receptors present inside the target cell are called intracellular receptors, mostly nuclear receptors (present in the nucleus).An excessive loss of fluid from the body can activate these receptors which stimulate the hypothalamus to release antidiuretic hormone (ADH) or vasopressin from the neurohypophysis.Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors located in the target tissues only.Binding of a hormone to its receptor leads to the formation of a hormone-receptor complex (Figureure 2 5 a, b).Hormone-Receptor complex formation leads to certain biochemical changes in the target tissue.There are separate areas of association where this sensory information is interpreted by putting it together with information from other receptors as well as with information that is already stored in the brain.Hormones which interact with intracellular receptors (e.g., steroid hormones, iodothyronines, etc.Each receptor is specific to one hormone only and hence receptors are specific.) mostly regulate gene expression or chromosome function by the interaction of hormone-receptor complex with the genome.Osmoreceptors in the body are activated by changes in blood volume, body fluid volume and ionic concentration.These receptors are usually located in our sense organs, such as the inner ear, the nose, the tongue, and so on.It has regions which receive sensory impulses from various receptors.So gustatory receptors will detect taste while olfactory receptors will detect smell.Hormones which interact with membrane-bound receptors normally do not enter the target cell, but generate second messengers (e.g., cyclic AMP, IP3, Ca++ etc) which in turn regulate cellular metabolism (Figureure 2 5a).An increase in body fluid volume can switch off the osmoreceptors and suppress the ADH release to complete the feedback.
