Term that refers to a membrane potential of about -70 mv?
Resting membrane potential
Is equilibrium potential the same as resting potential?
The equilibrium potential refers to the electrochemical potential at equilibrium of a particular ion, as calculated by the Nernst equation. The resting potential refers to the weighted average based upon membrane permeabilities of all the equilibrium potentials of the various ions in a given cell, as calculated by the Goldman equation.
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)
Do all cells have a resting potential of -70mV?
No there is a range of resting potentials. For example retinal ganglion cells have a resting potential of -65 mV while the endocochlear potential is +80 mV.
What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
A resting motor neuron is expected to?
exhibit a resting potential that is more negative than the "threshold" potential.
If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.
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 a difference in electric charge called?
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.
What is the inside charge of a nerve at its resting potentail?
Neurons have a resting membrane potential of approximately -70mV. Muscle cells have a resting membrane potential of approximately -90mV.
When a cell is at rest?
resting potential
