The Refractory Period definitions Flashcards

A phase during an action potential where a neuron is less responsive to stimuli, ensuring distinct action potentials.

A rapid rise and fall in voltage across a cell membrane, essential for nerve signal transmission.

A phase where no new action potentials can be initiated, ensuring unidirectional signal propagation.

A phase following the absolute period where a stronger stimulus is needed to initiate an action potential.

Membrane proteins that open in response to voltage changes, crucial for action potential initiation.

The state of a neuron when it is not transmitting an action potential, typically at -70 millivolts.

An increase in membrane potential making the inside of the cell more negative, occurring during the relative refractory period.

A decrease in membrane potential, making the inside of the cell less negative, essential for action potential initiation.

The one-way travel of an action potential along an axon, ensured by the refractory periods.

The frequency at which a neuron can generate action potentials, limited by the absolute refractory period.

Membrane proteins that allow potassium ions to pass, involved in returning the cell to resting potential.

The critical level to which a membrane potential must be depolarized to initiate an action potential.
