The electrical charge reversal in a cell when the electric potential changes from a resting state to an active state is known as an action potential. During an action potential, there is a rapid influx of sodium ions (Na+) followed by an efflux of potassium ions (K+), leading to a temporary reversal of the membrane potential. This process is crucial for the transmission of signals in neurons and muscle cells.
When a cell is in action, the electrical potential becomes more positive compared to the resting state. This is due to an influx of positively charged ions such as sodium. During the resting state, the electrical potential is negative, maintained by the concentration gradient of ions across the cell membrane.
The reversal of electric potential in a cell during action versus resting states is known as an "action potential." In a resting state, the cell membrane maintains a negative internal charge, but when stimulated, ion channels open, leading to a rapid influx of sodium ions. This shift causes depolarization, resulting in the action potential that propagates along the neuron or muscle cell. Afterward, the cell repolarizes, returning to its resting state.
The electrical charge of an inactive neuron is known as the resting membrane potential. This refers to the difference in charge across the neuron's cell membrane when it is not sending or receiving signals.
Action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, which include neurons, muscle cells, and endocrine cells, as well as in some plant cells. In neurons, they play a central role in cell-to-cell communication.
Although there are many polar molecules in a resting neuron the overall charge is zero. Neurons don't actually send electrical pulses in the same way as computers or other electric circuits. The main neural transmitter that carries a charge across the synapse is acetylcholine not individual electrons.

During the resting state, the electrical potential is negative, maintained by the concentration gradient of ions across the cell membrane.
The sudden reversal of the resting potential of a neuron is known as an action potential. This occurs when a neuron is stimulated past a certain threshold, leading to the rapid influx of sodium ions (Na+) into the cell and a temporary shift in membrane potential from negative to positive. This change propagates along the axon, allowing for the transmission of electrical signals within the nervous system. Following the action potential, the neuron undergoes a process called repolarization, returning to its resting potential.
The reversal of the resting potential owing to an influx of sodium ions is called depolarization. This occurs when the membrane potential becomes less negative, bringing it closer to the threshold for action potential initiation.
This is the definition of "resting potential".
The electrical charge of an inactive neuron is known as the resting membrane potential. This refers to the difference in charge across the neuron's cell membrane when it is not sending or receiving signals.
This electrical charge is called the resting membrane potential. It is generated by the unequal distribution of ions such as sodium, potassium, chloride, and calcium inside and outside the cell. The resting membrane potential plays a crucial role in cell communication and proper functioning of the nervous system.
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 resting potential of a cell is the membrane potential when the cell is at rest, typically around -70 millivolts. Membrane potential refers to the difference in electrical charge across the cell membrane. Resting potential is a type of membrane potential that is maintained when the cell is not actively sending signals.

The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
