Web19 okt. 2024 · What Are the Different Phases of an Action Potential? There are five cardiac action potential phases, numbered 0 through 4 (scientists get strange ideas sometimes). Phase 0 is depolarization of the membrane and the opening of "fast" (i.e., high-flow) sodium channels. Potassium flow also decreases. Web8 mrt. 2024 · The cardiac cycle comprises all of the physiological events associated with a single heartbeat, including electrical events, mechanical events (pressures and volumes), and heart sounds. The cardiac cycle is essentially split into two phases, systole (the contraction phase) and diastole (the relaxation phase).
Web1 mrt. 2011 · Real-time observation of the avian stage 13 looping heart reveals that interactions between the endocardial and myocardial compartments are more complex than previously depicted.
