A stimulus causes a change in permeability of neural membranes, which begins the process of transmitting an impulse. If the stimulus reaches the threshold potential of a neuron, an action potential is generated. Select the numbers of the statements below that occur once the threshold potential is reached. 1. Sodium ions flow into the neuron. 2. Sodium ions flow out of the neuron. 3. The membrane potential becomes positive. 4. The membrane potential becomes negative. 5. Voltage-gated potassium channels open. 6. Voltage-gated potassium channels close. 7. Potassium ions flow into the neuron. 8. Potassium ions flow out of the neuron.
