Skeletal muscle action potentials
The cardiac action potential differs from the neuronal action potential by having an extended plateau, in which the membrane is held at a high voltage for a few hundred milliseconds prior to being repolarized by the potassium current as usual. This plateau is due to the action of slower calcium channels opening and holding the membrane voltage near their equilibrium potential even after the s… Webb3 juni 2024 · Action potentials are used to send information throughout the body, and they are also necessary for some types of cells to function as they trigger intracellular processes (such as contraction of muscle cells). Cells that use action potentials are also called excitable cells and include: neurons, muscle cells (skeletal, cardiac, and smooth ...
