{wiki=Ball_and_chain_inactivation}
Ball and chain inactivation is a mechanism by which certain types of ion channels, particularly voltage-gated sodium (Na⁺) channels, become inactive after they have opened in response to a change in membrane potential. This process is crucial for the proper functioning of action potentials in excitable tissues, such as neurons and muscle cells.
