Answer :
Threshold potential describes the minimum level to which a membrane must be depolarised in order for an action potential to be fired.
The minimal magnitude required to start an action potential is known as the threshold potential. The voltage-gated sodium (Na+) ion channel opens in response to membrane an action potential, resulting in a rapid depolarization. The crucial level at which a membrane potential must depolarize membrane in order to start an action potential is known as the threshold potential. In neuroscience, threshold potentials are essential for controlling and propagating membrane signals in the peripheral and central nervous systems.
