One strong possibility for the cause of this scenario is a hoof abscess--a localized accumulation of pus within the horse's hoof. The good news is that abscesses can often be resolved quickly and easily with proper veterinary care and leave no lasting damage.
A: The sodium-potassium pump is an essential cellular membrane protein that functions by pumping out three sodium ions and taking in two potassium ions. This mechanism preserves the electrochemical gradient formed from the varying concentrations of sodium and potassium ions within the cell and its exterior. Continue Reading
This electrical potential gradient, created by the sodium-potassium pump, helps generate muscle contractions and regulates the heartbeat. Another of the pump's most important functions is preventing the swelling of cells. If sodium is not pumped out, water accumulates within the cell causing it to swell and ultimately burst.
