Seven numbered pоints mаrk different stаges оf аn actiоn potential. Point 1 is located on a horizontal line at approximately negative 80 millivolts, representing the resting potential. Point 2 marks the beginning of a gradual upward curve as the membrane potential rises toward the threshold line at negative 50 millivolts. Point 3 is positioned just before the membrane potential crosses the threshold, where the curve begins to steepen. Point 4 is at the peak of the action potential, where the membrane potential reaches approximately positive 30 millivolts. Point 5 marks the beginning of the downward phase as the membrane potential rapidly decreases. Point 6 indicates the lowest point of a slight dip below the resting potential, reaching approximately negative 90 millivolts. Point 7 is located on the horizontal line where the membrane potential returns to and stabilizes at the resting potential level. A nerve cell that receives a stimulus begins to depolarize; sodium channels open, allowing sodium to diffuse into the cell. An action potential may be generated if the stimulus is great enough to reach a threshold depolarization. The cell re-polarizes when the sodium channels close and potassium channels open, allowing potassium out of the cell. Eventually the cell returns to resting potential. At the point labeled 1 on the graph above, what is happening in the nerve cell?
