The Amplitude of an Action Potential Depends in Part on the Amount

question 98

Essay

The amplitude of an action potential depends in part on the amount of sodium in the extracellular fluid.Stanley Student has carefully impaled a neuron with an intracellular electrode.He tests the role of extracellular sodium by changing the concentration in the bathing fluid and recording an action potential after each change.The data he generated are shown in the table,where amplitude listed is the peak amplitude of the action potential; make an appropriate graph.
