Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
The restoration of the original charge to a nerve cell is called repolarization. This process involves the movement of ions across the cell membrane to reset the cell's resting membrane potential.
The electrical charge in nerves is caused by the movement of ions, such as sodium and potassium, across the nerve cell membrane. This movement creates a difference in electrical charge between the inside and outside of the cell, known as the membrane potential. When a nerve is stimulated, this membrane potential changes, allowing for the transmission of electrical signals along the nerve cell.
Mechanical stimulation of a nerve physically opens ion channels in the cell membrane, allowing ions such as sodium and potassium to flow across the membrane. This creates a change in the electrical charge inside the nerve cell, leading to depolarization and generation of an action potential.
you would say what a nerve cell is made of (cell wall, nucleus, membrane...) and then maybe put a diagram at the bottom of your explanation so the reader can fully understand what you mean.
The inside of a nerve cell is negatively charged at its resting potential, typically around -70 millivolts. This resting membrane potential is maintained by the differential distribution of ions across the cell membrane, with more sodium and calcium ions outside the cell and more potassium ions inside.

The most common type of phospholipids in the cell membrane of nerve cells are phosphatidylcholine and phosphatidylethanolamine, which together make up a majority of the lipid bilayer. These phospholipids help maintain the structural integrity and fluidity of the cell membrane, which is crucial for proper nerve cell function.

A component is the Sodium ion channel.
It is an integral part of the nerve cell membrane
The resting membrane potential of a nerve cell or muscle cell is typically around -70 millivolts. This electrical potential is maintained by the unequal distribution of ions across the cell membrane, with more negative ions inside the cell than outside. This resting potential is essential for the cell to respond to changes in its environment and generate electrical signals when needed.
the "plasma" membrane encases the "exterior" portion of the cell ... human cell walls are comprised of a cellular or "plasma" membrane. the plasma membrane is also called the phoso-lipid bilayer
Membrane capacitance refers to the ability of a cell membrane to store electrical charge. It plays a crucial role in the electrical properties of a cell by allowing the membrane to hold and release electrical energy, which is essential for processes like cell signaling and nerve impulses.

During electrochemical discharge of a nerve cell, an action potential is generated through the movement of ions across the cell membrane. This process involves the opening and closing of ion channels, leading to rapid changes in membrane potential. The action potential travels along the nerve cell, enabling communication between cells in the nervous system.
Mechanical stimulation of a nerve physically opens ion channels in the cell membrane, allowing ions such as sodium and potassium to flow across the membrane. This creates a change in the electrical charge inside the nerve cell, leading to depolarization and generation of an action potential.
They are both comprised of cells. Their cells both have a nucleus and cell surface membrane.
