carrier impulses from the CNS to the periphery‚ the peripheral nerves in turn have the funsion to carry messages from one part of the organism to another‚ so we can understand the action of these drugs. They act in the prevention‚ generation and propagation of the nervous impulse. Acting on the blocking of the depolarization initiation‚ allowing Na + to enter the nerve cell from rest to the trigger threshold (- 50a - 60 mV) would consequently impede the initiation and propagation of the impulse. Therefore

The neurons of the heart are not directly controlled by the human body’s central or peripheral nervous systems. Even without stimulation of the nerves‚ the heart will continue to beat at a steady rate (Wibbels & Vickery 2007). That
