The Home Delivered Meals Program provides nutritionally-balanced, hot meals during the day to homebound persons. Some people also receive cold, bagged meals so that they will have food available in the evening as well. Eligibility.
Potential, Spike. a large and sudden change in electrical potential that accompanies excitation in nerve and muscle cells and fibers. In physiology, the term âspike potentialâ is often used as a synonym for action potential. In clinical electroencephalography spike potential refers to gross potentials reaching 10 milliseconds in duration that are outwardly similar to the action potential of a nerve.
point, some of the sodium ions that enter the cell diffuse to the next section of the axon, raising the charge past the threshold of excitation and triggering a new influx of sodium ions. The action potential moves all the way down the axon to the terminal buttons. The action potential is an all-or-none phenomenon. In simple terms, this means that an incoming signal from another neuron is either sufficient or insufficient to reach the threshold of excitation.
