refraktaariperiodi
Refraktaariperiodi, also known as the refractory period, is a critical phase in the physiological process of nerve cell (neuron) excitation and signal transmission. It refers to the time interval during which a neuron cannot generate another action potential, regardless of the strength of the stimulus. This period follows the firing of an action potential and is essential for maintaining the orderly and efficient transmission of neural signals throughout the nervous system.
The refractory period is divided into two distinct phases: the absolute refractory period and the relative
The refractory period ensures that action potentials are discrete, all-or-none events, preventing continuous firing and signal
In clinical contexts, abnormalities in the refractory period can be associated with various neurological and cardiac
