Arrange the following steps in the correct sequence for the
conduction of a nerve impulse.
-The sodium-potassium pump restores the normal ion balance by
moving sodium out of the neuron and potassium back in.
-A stimulus increases the permeability of the neuronal
membrane.
-Potassium ions exit the neuron, restoring a negative charge
inside the cell.
-An action potential is generated and travels along the axon.
-Sodium ions rush into the neuron, causing depolarization.
-The action potential jumps from one node of Ranvier to the
next in myelinated fibers Correct Answers 1. A stimulus
increases the permeability of the neuronal membrane.
2. Sodium ions rush into the neuron, causing depolarization.
3.: An action potential is generated and travels along the axon.
4; Potassium ions exit the neuron, restoring a negative charge
inside the cell.
5: The sodium-potassium pump restores the normal ion balance
by moving sodium out of the neuron and potassium back in.
6: The action potential jumps from one node of Ranvier to the
next in myelinated fibers.
