What is the result of inhibitory neurotransmission on the postsynaptic membrane?
Hyperpolarization of the membrane. This inhibits action potential generation.
What substances plays a mojor role in generating the membrane potential of a neuron?
Well, for starters, membrane potential is a separation of charges across the membrane. So i think what you mean is "generating the action potential in a neuron". So in that case The substance that plays a major role in generating an action potential is Sodium (Na+). However, if you really mean membrane potential, there is only two substances associated with that and those are sodium (Na+) and potassium (K+).However, in truth, the generation of an action potential depends on the ligand and its receptor.
Term that refers to a membrane potential of about -70 mv?
Resting membrane potential
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.

Excessive vomiting for example can deplete the body's K reserves and abnormally lower the potassium concentration in the plasma hypokalemia The membrane potential of cells under the influence of?
somewhere between -65 and -90 mV

Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
Term that refers to a membrane potential of about -70 mv?
Resting membrane potential
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
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 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 does the difference in the K and Na concentration on either side of the plasma membrane and permeability of the membrane to those ions generate?
resting membrane potential
What is nernst potential-?
The Nernst potential refers to the reversal potential of the membrane potential at which there is no net flow of a particular number of ion from one side of the membrane to another.
What slight shift away from the resting membrane potential in a specific region of the plasma membrane is called a?
local potential
