, describe the polarization of a nerve at rest, inside of a cell is slightly (-) charged and
cell: outside is lightly (+) charged. (70 mv) difference.
describe the depolarization of a when there is an influx of Na+ ions and it causes
nerve cell: the cell to become depolarized with a (+) charge.
describe the repolarization of a begins immediately after depolarization with
nerve cell: potassium (+) ions leaving the cell in order to
restore equilibrium.
myelinated nerves conduct faster; less
impulses _________ with ________ energy.
what do the nodes of ranvier on the passage of local anesthesia into the nerve
myelinated nerves allow for? cell.
what is the primary action of local to block pain perception/transmission by
anesthetics? decreasing permeability of sodium ions.
where does the biotransformation in the pseudocholinesterase of blood plasma and
of esters occur? is then excreted by the kidneys.
