Respuesta :
Many ions—including K+, Na+, Ca2+, and Cl-—contribute to the resting membrane potential.
The individual ions contributing to the resting membrane potential of cardiac pacemaker cells, are sodium, potassium, and calcium ions.
What is resting membrane potential?
The resting membrane potential is the potential difference that exists between the inner and outer membranes of nerve cells when the cells are at rest or are not transmitting impulses.
For cardiac pacemaker cells, the individual ions contributing to the resting membrane potential are sodium, potassium, and calcium ions.
Therefore, calcium, potassium, and sodium ions contribute to resting membrane potential of cardiac pacemaker cells.
