Firing — refers to a decision made by an employer to terminate employment. Though such a decision can be made by an employer for a variety of reasons, ranging from an economic downturn to performance related problems on the part of the employee, being… … Wikipedia
Pacemaker potential — In the heart, the pacemaker potential is the voltage created by impulses from an artificial electronic pacemaker or the SA node which drives the rhythmic firing of the heart.The pacemaker potential brings the membrane potential to the threshold… … Wikipedia
Action potential — In physiology, an action potential is a short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in several types of animal cells, called… … Wikipedia
Postsynaptic potential — Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse. Postsynaptic potentials are graded potentials, and should not be confused with action potentials although their function is to… … Wikipedia
Excitatory postsynaptic potential — In neuroscience, an excitatory postsynaptic potential (EPSP) is a temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the postsynaptic cell. They are the opposite of inhibitory… … Wikipedia
Quick-firing gun — A quick firing gun (in U.S. parlance, rapid firing ) is an artillery piece, typically a gun or howitzer, which has several characteristics which taken together mean the weapon can fire at a fast rate.Quick firing was introduced worldwide in the… … Wikipedia
postsynaptic potential — ▪ biology a temporary change in the electric polarization of the membrane of a nerve cell ( neuron). The result of chemical transmission of a nerve impulse at the synapse (neuronal junction), the postsynaptic potential can lead to the… … Universalium
Quantitative models of the action potential — In neurophysiology, several mathematical models of the action potential have been developed, which fall into two basic types. The first type seeks to model the experimental data quantitatively, i.e., to reproduce the measurements of current and… … Wikipedia
Inhibitory postsynaptic potential — An Inhibitory Postsynaptic Potential (commonly abbreviated as IPSP) is the change in membrane voltage of a postsynaptic neuron which results from synaptic activation of inhibitory neurotransmitter receptors. The most common inhibitory… … Wikipedia
Pacemaker action potential — A pacemaker action potential is the kind of action potential that provides a reference rhythm for the network. This contrasts with pacemaker potential or current which drives rhythmic modulation of firing rate.Some pacemaker action potentials… … Wikipedia
Dismissal (employment) — Firing redirects here. For other uses, see Firing (disambiguation). Dismissal (referred to informally as firing or sacking) is the termination of employment by an employer against the will of the employee. Though such a decision can be made by an … Wikipedia
