The THC link you're looking for is https://t.me/+ZEm8kcmMaZ45OWEy Link to the tutorial from the video in the private "Heritage" club https://t.me/sechnov_legacy/100 Action Potential: A Complete and Clear Explanation for Medical Students and Doctors. In this video on normal physiology, we cover the action potential mechanism from A to Z in detail. You'll learn what the resting potential is, how potassium leak channels and the sodium-potassium pump (Na+/K+-ATPase) work. We'll explain the depolarization phase: the critical point of depolarization, voltage-gated sodium channels, and sodium ion entry into the cell. We'll examine the repolarization phase: voltage-gated potassium channels and potassium ion exit. We'll analyze the action potential graph in detail: spike, overshoot, and after-potentials (negative and positive). We explain refractory periods: the absolute refractory phase and the relative refractory phase, when the cell is non-excitable. This is the foundation for understanding the function of neurons, the heart, and the nervous system. Topics for exams in physiology, biochemistry, pharmacology, and pathophysiology. Suitable for preparation for Russian and international exams.
