The resting potential is the neuron "normal" state. The resting potential is around -70 millivolts (mV). An action potential is generated when membrain is depolarization to the threshold value. The...
Under normal circumstances action potential will proceed unilaterally. An action potential cannot proceed down an axon and depolarize in the reverse direction on the same axon. It must carry...
Pacemaker potentials are automatic potentials generated and are exclusively seen in the heart. They arise from the natural "leakiness" of the membrane that pacemaker cells have, resulting in passive...
In a normally functioning heart, the SA (sinoatrial) node is the pacemaker of the heart, but if it is nonfunctional then the AV (atrioventricular) node would take over. If it isn't working either...
