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.
Answers. Best Answer: Yes, depolarization is when contraction happens and repolarization is when the heart is relaxed. ;-) It may be easier to just think of what happens--the electrical impulse is what drives the contraction, so it's the electricity firing (depolarizing) that makes the heart contract.nswers.
