Voltage-gated ion channels have a crucial role in excitable cells such as neuronal and muscle tissues, allowing a rapid and co-ordinated depolarization in response to triggering voltage change. Found along the axon and at the synapse, voltage-gated ion channels directionally propagate electrical signals. Voltage-gated ion-channels are usually ...
Ion Television is a television network based in the United States made up of 44 owned-and-operated stations and 194 network affiliates, 164 of which broadcast as digital subchannels. [ 1] The Ion-owned stations are a part of the Ion Media unit of Scripps Networks, a wholly-owned subsidiary of the E. W. Scripps Company.

Voltage-gated sodium channels ( VGSCs ), also known as voltage-dependent sodium channels ( VDSCs ), are a group of voltage-gated ion channels found in the membrane of excitable cells ( e.g., muscle, glial cells, neurons, etc.) with a permeability to the sodium ion Na +. They are the main channels involved in action potential of excitable cells.

Potassium channels are the most diverse group of the ion channel family. [2] [3] They are important in shaping the action potential, and in neuronal excitability and plasticity. [4] The potassium channel family is composed of several functionally distinct isoforms, which can be broadly separated into 2 groups: [5] the practically non ...
Ion channels are located within the membrane of all excitable cells, [ 3] and of many intracellular organelles. They are often described as narrow, water-filled tunnels that allow only ions of a certain size and/or charge to pass through. This characteristic is called selective permeability.
