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.
A principle of action potential generation. The depolarization process travels over the entire membrane but if it does not generate sufficient voltage to stimulate the next area of the membrane, the spread of depolarization stops.
