aktionpotentiaali
Aktion potentiaali, often translated as action potential, is a fundamental concept in neurobiology and cell physiology. It refers to a rapid, transient, and regenerative change in the membrane potential of a cell, most notably neurons and muscle cells. This electrical signal is crucial for transmitting information across cells, enabling communication within the nervous system and triggering muscle contractions.
The generation of an action potential is a complex process driven by the movement of ions across
Following the peak of depolarization, the sodium channels inactivate, and voltage-gated potassium channels open. The outward
