sodium/potassium pump
A false statement about a cell's resting membrane potential could be that it does not involve the movement of ions across the cell membrane. In reality, the resting membrane potential is primarily due to the unequal distribution of ions, such as sodium and potassium, across the membrane, maintained by ion channels and pumps.
Resting membrane potential is typically around -70mV and is maintained by the activity of ion channels that allow for the passive movement of ions across the cell membrane.
The stimuli that can change the resting membrane potential of a cell include changes in ion concentrations inside or outside the cell, neurotransmitter binding to receptors, and mechanical deformation of the cell membrane. These changes can lead to the opening or closing of ion channels, altering the flow of ions across the membrane and affecting the cell's resting membrane potential.
The inside membrane is negatively charged during the resting membrane potential, typically around -70mV. This is due to the uneven distribution of ions across the cell membrane, with more negatively charged ions inside the cell compared to outside.
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 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.

This is the definition of "resting potential".
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 inside of the cell membrane is negatively charged at resting potential because of an unequal distribution of ions, specifically more negatively charged ions inside the cell compared to outside. This creates an electrical potential difference across the membrane, known as the resting membrane potential.
The equilibrium potential is important in determining the resting membrane potential of a cell because it represents the voltage at which there is no net movement of ions across the cell membrane. At this point, the concentration gradient and electrical gradient for a specific ion are balanced, resulting in a stable resting membrane potential.

The sodium-potassium pump is responsible for maintaining the resting membrane potential of a neuron by actively pumping sodium ions out of the cell and potassium ions into the cell, against their concentration gradients. This creates an imbalance of ions across the membrane, contributing to the resting potential of the neuron.
