In a myelinated fiber only the initial segment in the trigger zone has voltage-regulated channels. FALSE Nitric oxide NO acts as a neuromodulator by altering synaptic function. Learn more about these two hormones and.

This hypothesized pathophysiology appears to be supported by the mechanism of action of antidepressants. Norepinephrine activity is efficiently terminated through inactivation by the enzymes catechol-O-methyltransferase COMT or monoamine oxidase MAO by reuptake into nerve endings or by diffusion from binding sites. Acetylcholine ___ binds to ligand-regulated gates and is the most common inhibitory neurotransmitter in the brain.

The autonomic effect on a target cell depends only on the neurotransmitter reaching that target cell. According to the monoamine hypothesis depression is caused by a decrease in the synaptic activity of connections that use norepinephrine and serotonin True or False. According to the monoamine hypothesis of mood disorders depression is a consequence of overexpression in one of these diffuse.

Epinephrine and norepinephrine sound alike and they also share many of the same functions. Prominent biogenic amines include acetylcholine epinephrine norepinephrine dopamine and serotonin. True False Question 60 25 points Which neurotransmitter is secreted by postganglionic sympathetic fibers.
