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 term refers to the chemical potential of hydrogen?
pH refers to the chemical potential of hydrogen.
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Why does the membrane have to pump sodium and potassium across the membrane and keeps pumping it?
The membranes of nerve Cells use the Sodium/Potassium pump system to charge It's membranes, for a reversal of this condition constitutes the discharge of this Action Potential - 'keeps pumping it' refers to recharging the membrane's Action Potential.

What was the effect of curare on eliciting an action potential?
It creates an action potential
An electrical impulse moving down an axon is called?
This is called action potential. Action potential is the change in electrical potential that occurs between the inside and outside of a nerve or muscle fiber when it is stimulated, serving to transmit nerve signals.
The action potential is generated when a stimulus?
When a stimulus stimulates a neuron above the threshold, the action potential is generated.
Why does curare create an action potential?
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
Why does curare appear to generate an action potential?
It doesn't. I prevents an action potential from forming.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Also called a nerve impulse transmitted by axons?
action potential
Why does the membrane have to pump sodium and potassium across the membrane and keeps pumping it?
The membranes of nerve Cells use the Sodium/Potassium pump system to charge It's membranes, for a reversal of this condition constitutes the discharge of this Action Potential - 'keeps pumping it' refers to recharging the membrane's Action Potential.
What is the difference between a compound action potential and a single action potential?
Single action potentials follow the "all or none" rule. That is, if a stimulus is strong enough to depolarize the membrane of the neuron to threshold (~55mV), then an action potential will be fired. Each stimulus that reaches threshold will produce an action potential that is equal in magnitude to every other action potential for the neuron. Compound action potentials do not exhibit this property since they are a bundle of neurons and have different magnitudes of AP's. Thus compound action potentials are graded. That is, the greater the stimulus, the greater the action potential.
Do axons carry action potentials away from the cell body?
The areas that have had the action potential are refractory to a new action potential.
