sodium channels

Sodium channels are specialized proteins found in cell membranes, primarily in nerve and muscle cells. They act like gates that open and close to control the flow of sodium ions into and out of cells. When a nerve cell gets activated, these channels open, allowing sodium ions to rush in, which generates an electrical signal. This signal is crucial for transmitting messages throughout the nervous system and for muscle contractions. Proper functioning of sodium channels is essential for bodily functions, and issues with them can lead to various health problems, including certain neurological disorders.
