Dochádza k jej depolarizácii až obráteniu polarity membrány (transpolarizácia). Následne dochádza k rýchlemu návratu do pôvodného stavu – repolarizácii. </p><p>Spočiatku dochádza k zvýšenému vtoku Na<sup>+</sup> do bunky. Cca. do úrovne 15 mV je schopný únik K<sup>+ </sup> z bunky túto nerovnováhu kompenzovať. Po dosiahnutí spúšťacej úrovne (prahu dráždivosti) dochádza k náhlemu skokovému zvýšeniu priepustnosti membrány pre Na<sup>+</sup> v dôsledku otvorenia napäťovo riadených sodíkových kanálov, čo spôsobuje reťazovú reakciu a aktiváciu ďalších transportných systémov pre <a href="/wiki/Sod%C3%ADk" title="Sodík">sodík</a>. Nastáva depolarizácia membrány. <br />Vzostup priepustnosti membrány pre Na<sup>+</sup> sleduje s miernym oneskorením K<sup>+</sup>, ktorého ióny naopak bunku opúšťajú. To neskôr umožní repolarizáciu a návrat do stavu pokojového membránového potenciálu. Počas akčného potenciálu teda dochádza k výmene určitého (celkovo veľmi malého) množstva iónov sodíka a draslíka na stranách membrány. Táto výmena následne prebieha opačným smerom, kedy aktívne transportné systémy (využívajúce energiu <a href="/wiki/ATP" class="mw-disambig" title="ATP">ATP</a>) vracajú draslík do bunky a sodík von z bunky. </p> <div class="mw-heading mw-heading2"><h2 id="Následky"><span id="N.C3.A1sledky"></span>Následky</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ak%C4%8Dn%C3%BD_potenci%C3%A1l&veaction=edit&section=2" title="Upraviť sekciu: Následky" class="mw-editsection-visualeditor"><span>upraviť</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ak%C4%8Dn%C3%BD_potenci%C3%A1l&action=edit&section=2" title="Editovat zdrojový kód sekce Následky"><span>upraviť zdroj</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Po dosiahnutí prahu dráždivosti a spusteniu kaskády vedúcej k vzniku akčného potenciálu je bunková membrána v príslušnej časti absolútne nereaktívna – nereaguje na žiaden stupeň stimulácie. Tento stav sa označuje ako <i>absolútna refraktérna fáza</i>. Tesne na konci hrotovej fázy („peaku“) sa stáva membrána opäť dráždivou, no stimul musí byť značne silnejší ako v základnom pokojovom stave – táto fáza sa označuje ako <i>relatívna refraktérna fáza</i>. Táto vlastnosť membrány dáva čas bunke na regeneráciu pomerov koncentrácii iónov na stranách membrány. </p> <div class="mw-heading mw-heading2"><h2 id="Vlastnosti">Vlastnosti</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ak%C4%8Dn%C3%BD_potenci%C3%A1l&veaction=edit&section=3" title="Upraviť sekciu: Vlastnosti" class="mw-editsection-visualeditor"><span>upraviť</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ak%C4%8Dn%C3%BD_potenci%C3%A1l&action=edit&section=3" title="Editovat zdrojový kód sekce Vlastnosti"><span>upraviť zdroj</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Akčný potenciál vzniká na určitom mieste bunkovej membrány a má tendenciu sa z miesta vzniku šíriť – depolarizácia membrány totiž aktivuje postupne ďalšie a ďalšie napäťovo riadené kanály pre Na<sup>+</sup>. Takýmto spôsobom sa šíri nervový vzruch po axónoch (neuritoch) <a href="/wiki/Neur%C3%B3n" title="Neurón">nervových buniek</a> smerom od tela a po dentritoch smerom k telu bunky. Dôležitou vlastnosťou vzruchu je to, že jeho charakter sa vzdialenosťou od miesta vzniku nemení, amplitúda je stále rovnako vysoká. Zároveň absolútna a relatívna refraktérna fáza zabraňuje spätnému šíreniu akčného potenciálu k miestu vzniku. </p><p>Na <a href="/wiki/Myeliniz%C3%A1cia" title="Myelinizácia">nemyelinizovaných</a> nervových vláknach sa vzruch šíri kontinuálne a relatívne pomaly. Značná časť axónov nervových buniek je ale myelinizovaná a vzruch sa šíri skokovo dráždením drobných „neizolovaných“ medzier (Ranviérove zárezy) – tento spôsob vedenia vzruchu sa označuje ako <i>saltatórny</i> a jeho zásadnou výhodou je značne vyššia rýchlosť a energetická hospodárnosť (v podstate sa depolarizujú len krátke úseky membrány a teda návrat do rovnováhy je značne menej náročný na spotrebu ATP). Myelínová pošva zároveň bráni aktivácii susedných nervových vlákien, ktoré často prebiehajú v tesnej blízkosti. </p> <div class="mw-heading mw-heading2"><h2 id="Zdroj">Zdroj</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ak%C4%8Dn%C3%BD_potenci%C3%A1l&veaction=edit&section=4" title="Upraviť sekciu: Zdroj" class="mw-editsection-visualeditor"><span>upraviť</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ak%C4%8Dn%C3%BD_potenci%C3%A1l&action=edit&section=4" title="Editovat zdrojový kód sekce Zdroj"><span>upraviť zdroj</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><cite style="font-style:normal">KITTNAR, Otomar a kol. <i>Lékařská fyziologie</i>.
