Answer Details
The two cations involved in the action potential of nervous transmissions are sodium (Na+) and potassium (K+). During the resting state of a neuron, the concentration of sodium ions is higher outside the cell than inside, and the concentration of potassium ions is higher inside the cell than outside. When a stimulus is received by the neuron, it causes the opening of sodium channels, allowing sodium ions to flow into the cell, which results in a depolarization of the membrane potential. This depolarization triggers the opening of potassium channels, allowing potassium ions to flow out of the cell, which repolarizes the membrane potential back to the resting state. The movement of sodium and potassium ions across the neuron membrane generates the electrical signal, which is transmitted along the neuron axon as an action potential.
