Electrophysiology
The study of electrical properties and phenomena in biological systems.
Membrane Potential
The difference in charge across a cell membrane, which is generated by the separation of opposite charges.
Ion Channels
Proteins in the cell membrane that allow ions to cross the membrane, resulting in changes in charge and voltage.
Voltage-Gated Ion Channels
Ion channels that open and close in response to changes in membrane potential.
Ligand-Gated Ion Channels
Ion channels that open and close in response to the binding of molecules to the cell membrane.
Resting Membrane Potential
The stable voltage difference across the cell membrane of a neuron when it is not transmitting signals.
Na+/K+ Pump
A protein in the cell membrane that uses ATP to actively transport sodium ions out of the cell and potassium ions into the cell, maintaining the concentration gradients.
Graded Potential
Short-lived, localized changes in membrane potential that occur in response to a stimulus.
Action Potential
A brief, rapid change in membrane potential that allows neurons to transmit signals over long distances.
Propagation
The spread of an action potential from one area of the membrane to the next.
Conduction Velocity
The speed at which an action potential travels along an axon.
Axon Diameter
The width of an axon, which affects the resistance to the flow of ions and influences the conduction velocity.
Myelination
The presence of a myelin sheath around an axon, which allows for faster conduction of action potentials through saltatory conduction.
Continuous Conduction
Conduction of an action potential along a nonmyelinated axon, which is slower compared to saltatory conduction.
Saltatory Conduction
Conduction of an action potential along a myelinated axon, which is faster due to the jumping of the action potential between nodes of Ranvier.
