Ground-Glass Nodules: If Growing, Assume Cancer. Blair Westerly, MD. The more CT scans that are performed, the more ground-glass opacities (GGOâs) are seen and what to do with these abnormalities can be difficult to ascertain for clinicians.
the process of reversing the charge across a cell membrane (usually a NEURON), so causing an ACTION POTENTIAL. In depolarization, the inside of the membrane, which is normally negatively charged, becomes positive and the outside negative.
During depolarization of the plasma membrane, A) sodium ions move rapidly into the cell. B) potassium ions move rapidly out of the cell. C) membrane permeability to sodium ions decreases. D) the outside of the cell becomes positively charged relative to the inside.
