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.
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.
The following is a list of stations that are affiliated with Ion Plus, a television network in the United States owned by Ion Media Networks. The network was originally in operation from 2007 to 2021 with a total of 65 affiliates, the vast majority of which were owned by its corporate parent.

Scripps Company. The network first began broadcasting on August 31, 1998, as Pax TV, focusing primarily on family-oriented entertainment programming.
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.

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 ...
