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
The sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na+ and K+ at constant disequilibrium. The sudden shift from a resting to an active state, when the neuron generates a nerve impulse, is caused by a sudden movement of ions across the membraneâspecifically, a flux of Na+ into the cell.
