128
Q

Step 1 of cardiac muscle action potential?

A

Sodium flows in and depolarizes membrane

129
Q

Step 2 of cardiac muscle action potential?

A

When cell is depolarized, sodium channels close

130
Q

Step 3 of cardiac muscle action potential

A

Calcium enters membrane and prolongs depolarization and some potassium leaks out

131
Q

Step 4 of cardiac muscle action potential?

A

Potassium rapidly flows out and calcium channels close and it exits the cell

132
Q

Where do the different ions flow during a cardiac muscle action potential?

A

Potassium flows out, sodium flows in, calcium flows in

133
Q

What is a plateau?
