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.
As the calcium is pumped out of the cell and back into the SR, the90 mV.contractile cell relaxes.j. A small voltage change (of about 5 mV to about -85 mV) occurs, whichinitiates depolarization.20. (Page 13. ) Are neurotransmitters involved in the transmission ofdepolarization from one cardiac muscle cell to another?21. (Page .) Label the parts of this action potential tracing in contractilecells:A.
