Action Current

action current

[′ak·shən ‚kə·rənt] (physiology) The electric current accompanying membrane depolarization and repolarization in an excitable cell.

Current, Action

in physiology, the electric current that develops in nerve and muscle cells and in some plant cells between their excited areas and adjacent resting areas. It is caused by changes in the ionic permeability of the cell membrane and in potential that occur in the excited areas, and is recorded by extracellular electrodes. Action current plays an important role in the distribution of action potential along a cell or fiber.

action current

ac·tion cur·rent

an electrical current induced in muscle fibers when they are effectively stimulated; normally it is followed by contraction.

ac·tion cur·rent

(ak'shŭn kŭr'rĕnt) An electrical current induced in muscle fibers when they are effectively stimulated; normally it is followed by contraction.
