Action potential
In physiology, an action potential occurs when the membrane potential of a specific axon location rapidly rises and falls: this depolarisation then causes adjacent locations to similarly depolarise.

Axon
An axon (from Greek ἄξων áxōn, axis) or nerve fiber, is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses known as action potentials, away from the nerve cell body.

Axon hillock
The axon hillock is a specialized part of the cell body (or soma) of a neuron that connects to the axon.

Axon terminal
Axon terminals (also called synaptic boutons or terminal boutons) are distal terminations of the telodendria (branches) of an axon.

Biology
Biology is the natural science that studies life and living organisms, including their physical structure, chemical composition, function, development and evolution.

Cell (biology)
The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known living organisms.

Decamethonium
Decamethonium (Syncurine) is a depolarizing muscle relaxant or neuromuscular blocking agent, and is used in anesthesia to induce paralysis.

Electric charge
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.

Endothelium
Endothelium refers to cells that line the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall.

Hyperpolarization (biology)
Hyperpolarization is a change in a cell's membrane potential that makes it more negative.

Ion
An ion is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons).

Ion channel
Ion channels are pore-forming membrane proteins that allow ions to pass through the channel pore.

Membrane potential
The term "membrane potential" may refer to one of three kinds of membrane potential.

Molecular diffusion
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero.

Na+/K+-ATPase
-ATPase (sodium-potassium adenosine triphosphatase, also known as the pump or sodium–potassium pump) is an enzyme (an electrogenic transmembrane ATPase) found in the plasma membrane of all animal cells.

Neurotransmitter
Neurotransmitters are endogenous chemicals that enable neurotransmission.

Nicotinic agonist
A nicotinic agonist is a drug that mimics the action of acetylcholine (ACh) at nicotinic acetylcholine receptors (nAChRs).

Resting potential
The relatively static membrane potential of quiescent cells is called the resting membrane potential (or resting voltage), as opposed to the specific dynamic electrochemical phenomena called action potential and graded membrane potential.

Rod cell
Rod cells are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor, cone cells.

Sodium
Sodium is a chemical element with symbol Na (from Latin natrium) and atomic number 11.

Summation (neurophysiology)
Summation, which includes both spatial and temporal summation, is the process that determines whether or not an action potential will be triggered by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs (temporal summation).

Suxamethonium chloride
Suxamethonium chloride, also known as suxamethonium or succinylcholine, is a medication used to cause short-term paralysis as part of general anesthesia.

Threshold potential
In neuroscience, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential.

Voltage-gated calcium channel
Voltage-gated calcium channels (VGCCs), also known as voltage-dependent calcium channels (VDCCs), are a group of voltage-gated ion channels found in the membrane of excitable cells (e.g., muscle, glial cells, neurons, etc.) with a permeability to the calcium ion Ca2+.

Voltage-gated ion channel
Voltage-gated ion channels are a class of transmembrane proteins that form ion channels that are activated by changes in the electrical membrane potential near the channel.
