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 ...
Sodium channel. C is the sodium channel. Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na +) through a cell's membrane. [ 1][ 2] They belong to the superfamily of cation channels .
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.
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.

Police have arrested a 78-year-old man whose DNA sample matched evidence from the autopsy of a nursing student killed in 1980, Austin, Texas, police said in a press release.
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.
Transient receptor potential channel. Transient receptor potential channels ( TRP channels) are a group of ion channels located mostly on the plasma membrane of numerous animal cell types. Most of these are grouped into two broad groups: Group 1 includes TRPC ( "C" for canonical), TRPV ("V" for vanilloid ), TRPVL ("VL" for vanilloid-like), TRPM ...
