Answer:- … WebWhen chemically gated Cl- channels open in the membrane of a resting nerve cell, Cl- ions, which are negatively charged, move out of the cell and into the extracellular fluid. This results in an increased negative charge inside the cell, making it more negative than its resting potential. This increased negativity is called hyper polarization.
