The resting membrane potential in the auto rhythmic myocardiocytes cells of the heart is_

The resting membrane potential in the autorhythmic myocardiocytes, or pacemaker cells, of the heart is typically around -60 to -70 millivolts (mV). However, these cells are unique in that they do not have a stable resting membrane potential like other types of nerve or muscle cells. Instead, they gradually depolarize until they reach a threshold that triggers an action potential. The process of depolarization is referred to as "pacemaker potential" and is crucial for the generation of rhythmic heartbeats.
