Norepinephrine

Autor: Suzuki



Respuesta:

Noradrenergic neuron cell bodies are mainly located in the brain stem and the lateral tegmental area of the pons. These neurons fan out broadly to provide most regions of the CNS with diffuse noradrenergic input. Excitatory effects are produced by activation of α1 and β1 receptors. Inhibitory effects are caused by activation of α2 and β2 receptors. CNS stimulants (eg, amphetamines, cocaine), monoamine oxidase inhibitors (eg, phenelzine), and tricyclic antidepressants (eg, amitriptyline) are examples of drugs that enhance the activity of noradrenergic pathways.
