Norepinephrine (NE) released by sympathetic neurons can be reabsorbed by the nerve fiber (degraded by MAO), diffuse into adjacent tissues (degraded by COMT), or remain in circulation until degraded by the liver.
1. reabsorption by nerve fiber where it is broken down by MAO<div>2. Diffusion in adjacent tissues where it is degraded by catechol-o-methyltransferase (COMT)</div><div>3. remains circulation until it is degraded by liver</div>
