Anaes Vivas · Applied cardiovascular & respiratory physiology
Data viva — the neuronal action potential
A Primary data viva — read each phase of the action potential and link it to the ion movement and channel state that produces it; then contrast with the cardiac action potential and tie to anaesthetic drug action.

Prompt
A labelled graph of a single neuronal action potential is displayed (resting minus 70 mV, threshold minus 55 mV, upstroke, peak plus 30 mV, repolarisation, after-hyperpolarisation). Interpret the ionic events at each phase.
