_____ inhibits the firing of neurons in the central nervous system, but it excites the heart muscle, intestines, and urogenital tract.

Respuesta :

Norepinephrine. Intuitively, it is also called noradrenaline. The neural transmitter acts on noradrenergic receptors. Adrenal glands release the neurotransmitter into the bloodstream and is used in the sympathetic nervous system. The neurotransmitter is significant in the fight-or-flight response to stimuli.
