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.
The local potential is the depolarization of a cell below threshold. After the cell is sufficiently depolarized (and reaches threshold), it fires an action potential down the axon. The local potential is the depolarization of a cell below threshold. After the cell is sufficiently depolarized (and reaches threshold), it fires an action potential down the axon. Go
