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.
Many cells use electrical stimulation to communicate with each other. This process starts with depolarization. The lesson looks at the role of depolarization in the electrical communication within and between cells. AP Biology: Help and Review / Science Courses.
