"During the process of nerve impulse transmission, when sodium flows into the neuron, its cell membrane is"

During the process of nerve impulse transmission, when sodium flows into the neuron, its cell membrane is depolarized.

The nerve impulse is an electrical impulse, so that the electrical impulse is transmitted, the positive sodium ions that are present outside the neuron in a state of rest must pass through the cell membrane.

In a state of rest, the interior of the neuron has a negative electrical charge (repolarized membrane).

When positive sodium ions enter the neuron, they change the internal charge from negative to positive (depolarized membrane).

This increase is due to the constant number of sodium ions, positively charged, inside the membrane of the neuron.

This depolarization is the first step in the generation of an action potential, that is, the emission of a message.

In other words, it is the part of the process that causes an electrical signal to be released, which will end up traveling through the neuron to cause the transmission of information through the nervous system.

Therefore, we can conclude that during the process of nerve impulse transmission, when sodium flows into the neuron, its cell membrane is depolarized.

The neuron cell membrane is partially permeable to sodium ions, so sodium atoms slowly leak into the neuron through sodium leakage channels. The cell wants to maintain a negative resting membrane potential, so it has a pump that pumps potassium back into the cell and pumps sodium out of the cell at the same time.
