A series of similar stimuli that increases change in local membrane potential is called?
Action potential
When a stimulus is sufficiently great enough to change the membrane potential and propagate an action potential it is called?
recruitement
Why does the polarity of a cell membrane reverse during an action potential?
During an action potential the neuron receives a stimulus causing the cell membrane to become more permeable to sodium than potassium, calling the polarity to change.
The sudden reversal of electrical charge across the neuron membrane is called?
Action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, which include neurons, muscle cells, and endocrine cells, as well as in some plant cells. In neurons, they play a central role in cell-to-cell communication.
What is depolorization?
Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.
What change in membrane potential triggers action potential?
depolarization
What change in membrane potential depolarization or hyperpolarization triggers an action potential?
despolarization
What is the rapid change in membrane's potential caused by the deplariztion of a neuron?
action potential
A series of similar stimuli that increases change in local membrane potential is called?
Action potential
What is the small change in the charge across a neuron's membrane called?
Action Potential
When a stimulus is sufficiently great enough to change the membrane potential and propagate an action potential it is called?
recruitement
An action potential is a travelling change in the axon's membrane permeability resulting in a flow of?
ions

Electrical change in the neuronal membrane that is transmitted along axon is?
Action potential is the term for an electrical change in the neuronal membrane transmitted along an axon. The axon is part of a nerve cell that conducts impulses.
What is the meaning of action potential-use dependence?
When chemicals contact the surface of a neuron, they change the balance of ions (electrically charged atoms) between the inside and outside of the cell membrane. When this change reaches a threshold level, this effect runs across the cell's membrane to the axon. When it reaches the axon, it initiates the action potential, which is a rapidly moving exchange of ions.
What is depolorization?
Depolarization is a change in a cell's membrane potential, making it more positive, or less negative. In neurons and some other cells, a large enough depolarization may result in an action potential.
