What is the difference between the release of catecholamines from the adrenal medulla and the postganglionic sympathetic neurons in the autonomic nervous system (ANS)?
1. The postganglionic sympathetic neurons of the ANS release catecholamines into the systemic circulation, while the adrenal medulla releases catecholamines that affect only body cells innervated by the ANS.
2. The postganglionic sympathetic neurons of the ANS release catecholamines that are deactivated by the kidneys, while the catecholamines released from the adrenal medulla are deactivated by adrenergic enzymes.
3. The release of catecholamines from the adrenal medulla are longer-lasting than those produced by the postganglionic sympathetic neurons of the ANS.
4. The concentrations of catecholamines are shortened, reducing their effect on body cells, when released from the adrenal medulla, as opposed to the postganglionic sympathetic neurons of the ANS, which have long-lasting effects.
