Target type: biologicalprocess
The process in which atrial cardiac muscle cell membrane potential changes in the depolarizing direction from the negative resting potential towards the positive membrane potential that will be the peak of the action potential. [GOC:dph, GOC:mtg_cardiac_conduct_nov11, GOC:tb]
Membrane depolarization during atrial cardiac muscle cell action potential is a complex process that initiates the electrical signal responsible for atrial contraction. It begins with the influx of sodium ions (Na+) through fast sodium channels, driven by the electrochemical gradient. This influx rapidly increases the membrane potential, resulting in a steep and rapid depolarization phase. The depolarization phase is followed by a plateau phase where the membrane potential remains relatively stable. During this phase, calcium ions (Ca2+) enter the cell through L-type calcium channels, contributing to the sustained depolarization and triggering muscle contraction. The plateau phase is characterized by a balance between calcium influx and potassium efflux. Finally, the repolarization phase occurs as potassium ions (K+) leave the cell through potassium channels, restoring the membrane potential back to its resting value. The process is crucial for maintaining the rhythmic contractions of the atria, ensuring efficient blood flow from the atria to the ventricles.'
