Mini Episode: The Saga of the Cardiac Action Potential

Action potentialSodium/Potassium ATPase pumps create more positively charged ions outside the cell than inside the cell, this creates a relative negative charge in the cellPhase 4- Resting (~ -90 mv)Phase 0- Sodium enters the cell (+10 mv) Phase 1- Potassium efflux from cell as now there is no negative charge holding it in (0 mv) Phase 2- Calcium channels open and allow calcium in, calcium triggers the ryandoine receptor and allows for calcium dependent calcium release from the sarcoplasmic reticulum occursPhase 3- Potassium continues to leave the cell  allowing return to -90 mv A Morel DilemmaSupport the showReview the show where ever your listeningGet Messages from Toxo (Join the Newsletter!)Join as a supporting memberAd free episodesBonus content and early accessDiscounts and give aways on GOTA PICCEM Mushroom card gameThe GOTTA PICCEM Poisonous Mushroom Game!The Poisonus Fungus Amongus Children's Book!Full book reading (6 minutes!)Tox trinkets (Rep the show at home!)Reach the showEmail: [email protected] Show ResourcesRyan's Medical Games and ResourcesShow Website
