Webb12 mars 2024 · The electrical impulse originates in the sinus node. From there, it spreads across the right atrium and the left atrium (the top two chambers of the heart), causing both atria to contract. This is referred to as atrial depolarization, an action that pushes blood into the right and left ventricles, the bottom two chambers of the heart. 5 WebbExercise 3: Neurophysiology of Nerve Impulses Activity 3: The Action Potential: Threshold Name: Rachael Villaran Date: 12 July 2024 Session ID: session-b6187957-ccca-a70d-6aa4-83a87c. ...
