Ciprofloxacin is an antibacterial prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment and prevention of certain bacterial infections, including: Urinary tract infections. Lower respiratory tract infections.
In neurophysiology Hyperpolarization is a change in a cell's membrane potential that makes it more negative. It is the opposite of a depolarization.Hyperpolarization is often caused by efflux of K+ (a cation) through K+ channels, or influx of Clâ (an anion) through Clâ channels. On the other hand, influx of cations, e.g. Na+ through Na+ channels or Ca2+ through Ca2+ channels, inhibits hyperpolarization.t is the opposite of a depolarization. Hyperpolarization is often caused by efflux of K+ (a cation) through K+ channels, or influx of Clâ (an anion) through Clâ channels. On the other hand, influx of cations, e.g. Na+ through Na+ channels or Ca2+ through Ca2+ channels, inhibits hyperpolarization.
Depolarization and hyperpolarization occur when ion channels in the membrane open or close, altering the ability of particular types of ions to enter or exit the cell. For example: The opening of channels that let positive ions flow out of the cell (or negative ions flow in) can cause hyperpolarization.
