Nerve Impulses

Nerve Impulses Depolarization –

Nerve Impulses Hyperpolarization –

Nerve Impulses Repolarization –

Nerve IMpulses 3 Phases

Phase 1 - Resting Phase

Phase 2 – Action Potential Occurs in 4 steps

Step 1 – Depolarization to threshold

Step 2-Rapid Depolarization

Step 3 – Sodium closes, potassium Opens

Step 4 - Hyperpolarization

Phase 3 - Recovery
