Stress and Anxiety. Dogs are sensitive animals; excessive stress or anxiety in their lives can cause hair loss. Sometimes hair loss is a bodily physical manifestation of stress, but other times anxious dogs will partake in compulsive licking that leads to hair loss in areas they lick too much. Dogs may get stressed or anxious due to a number of reasons, including confinement, bullying from other pets in the house, separation anxiety and past trauma or abuse.
Confidence votes 1.2K. Sodium. A positive ion (cation) that enters the cell (influx) rapidly when the membrane threshold is reached and the voltage gated sodium channels open. This occurs during the rising phase of an action potential, i.e. membrane depolarization beyond the threshold for activation.
Describe the movement of sodium and potassium ions across a neuron's membrane during resting potential: there is a slight leakage of sodium ions and potassium ions during resting potential sodium diffuses from outside, where it is higher in concentration, to the inside potassium diffuses in the opposite direction, since it is more concentrated inside the neuron What does the Sodium Potassium ATPase do to the flux of ions across the gradients? the sodium potassium pump maintains concentration gradients for the two ions by pumping sodium out of the cell and potassium back into the cell
