When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
What is the chief positive intracellular ion in a resting neuron?
The chief positive intracellular ion in a resting neuron is a potassium ion. Just inside the cell of a resting neuron, the membrane is negative.
What is the approximate resting potential of a neuron?
It is -70 millivolts. The resting potential of a neuron refers to the voltage difference across the plasma membrane of the cell, and is expressed as the voltage inside the membrane relative to the voltage outside the membrane. The typical resting potential voltage for a neuron is -70mV Resting potentials occur because of the difference in concentration of ions inside and outside of the cell, largely by K+ (Potassium ions) but some contribution is made by Na+(Sodium ions)
What is membrane polarity?
-70 mV this potential difference in a resting neuron (Vr) is called the resting membrane potential, and the membrane is said to be polarized.
What is the difference in electrical charge across the cell membrane of a resting neuron is called?
This is the definition of "resting potential".
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
When a neuron is resting the inside of the cell membrane is?
When a neuron is resting then inside of the cell membrane is more negative than outside.
The resting membrane potential of a neuron is about?
-70mV
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
_____ is the process by which the neuron regains its negative resting membrane potential?
Repolarization
What is the chief positive intracellular ion in a resting neuron?
The chief positive intracellular ion in a resting neuron is a potassium ion. Just inside the cell of a resting neuron, the membrane is negative.
What is a sudden electrical charge in a neuron membrane is?
Yes.
Which condition is a neuron in when the outside of the neuron has a net positive charge and the inside has a negative charge?
resting potiental

How electrical signal exist related with membrane potential and and action potential?
Resting potential and action potential are both names for the measure of electrical voltage within the membrane of a cell. Specifically, these terms are used in describing the transfer of information along neural pathways. Resting potential is a state where cells are at rest. However, if an electrical response or depolarization reaches threshold, then ion channels open, allowing sodium ions to rush into the membrane and increase the voltage measure, firing an action potential along the length of this membrane.
