toiminnanapotentiaalin
Toiminnanapotentiaali, often translated as action potential, is a fundamental concept in neurobiology and physiology. It describes a rapid, transient change in the electrical potential across the membrane of a cell, most notably nerve and muscle cells. This electrical signal is crucial for communication within the nervous system and for muscle contraction.
The generation of an action potential is triggered by a stimulus that causes the cell membrane to
Once initiated, an action potential propagates along the cell membrane without diminishing in strength. In neurons,
