Question

I struggled with this question. Can you help me, please?

For the myocardial cells the RMP is at (-85/0/+20/-15) mV. As the action potential from the specialized cells reach these myocardial cells by gap junctions, (VGNA/Slow VGK/ VGCA/ Fast VGK) channels open and rushes in (sodium, potassium, calcium) causing depolarization of the membrane to (-85/0/+20). At this point the (VGNA/Slow VGK/ VGCA/ Fast VGK) channels close and (VGNA/Slow VGK/ VGCA/ Fast VGK) channels open causing (sodium, potassium, w w calcium) to move (in/out) of the cell and this brings the membrane potential to (VGNA/Slow VGK/ VGCA/ Fast (sodium, potassium, calcium) to enter the cell and we (-85/0/+20/-15) mV. At this point, VGK) channels also open causing see a plateau in the AP graph. The plateau continues for 200-300ms and then (VGNA/Slow VGK/ VGCA/ Fast VGK) channels open causing (sodium, potassium, calcium) to move (in/out) of the cell resulting in bringing the membrane potential back to -85mV.
