Where the drug binds in the body.

Opening Cl⁻ or K⁺ channels.

Enzymatic degradation.

Voltage-gated Na⁺ channels open rapidly.

Sodium-potassium pump.

A change in the postsynaptic membrane potential that makes it less likely to generate an action potential.

To maintain the resting membrane potential by moving Na⁺ out and K⁺ into the cell.

A rapid rise and fall in membrane potential that occurs when a neuron sends a signal.

A process where receptors become less responsive to a neurotransmitter after prolonged exposure.

To open or close in response to changes in membrane potential, allowing ions to flow across the membrane.
