Potencjał spoczynkowy i czynnościowy — jak neuron przesyła info! 📬🧠 Przewodzenie impulsu nerwowego

Final exams are just around the corner, and there's always time for inheritance problems! Check out my ebook and don't be surprised: https://www.naffy.io/karolina-klein/s... The neuron—the hero of the nervous system and the master of communication! 🧠 In this video, I break it down: from the head (i.e., the cell body), through the projections (dendrites and axon), to the mysterious axon hillock, where all the electrical action begins! ⚡ You'll see how "biological current" works in our body—what the resting potential and action potential are, why sodium and potassium ions play a key role here, and how gated ion channels work, reminiscent of bouncers in front of a club. 🎉 There will also be a few cool associations, and for dessert, you'll learn why without glial cells, neurons would be... a bit like a smartphone without a charger. 🔋 If you want to truly understand how nerve impulses are conducted—not just "mold it down"—this episode is for you! 📚 Perfect for final exams, college, and any curious mind! 🔔 Subscribe to the channel and catch up on another dose of neurobiology—coming soon: synapses and spike conduction. 00:00 Intro 00:08 Neuron Structure 01:59 Resting Potential 06:15 Action Potential, Impulse Waveform 09:36 Impulse Propagation 10:13 Synapse
