WebVasopressin, synthesized in the hypothalamus, is released by increased plasma osmolality, decreased arterial pressure, and reductions in cardiac volume. Three subtypes of vasopressin receptors, V1, V2, and V3, have been identified, mediating vasoconstriction, water reabsorption, and central nervous system effects, respectively. Vasopressin and its … WebDuring stress, much of the body’s energy is used to combat imminent danger. Kidney function is halted temporarily by epinephrine and norepinephrine.

WebThe norepinephrine transporter (NET) is situated in the presynaptic plasma membrane of noradrenergic neurons; this receptor is responsible for ∼90% of the norepinephrine (NE) uptake that is released in the synaptic cleft. Many antidepressants block this receptor, resulting in potentiation of NE actions in pre- and postsynaptic receptors.
