The duration of the plateau phase is largely dependent upon the effectiveness of the stimuli employed, combined with the factor of individual drive for culmination of sex tension increment.
During orgasmic phase, the specific response of the vaginal barrel to the explosive physiologic entity of orgasm is confined to the orgasmic platform in the outer third of the vagina.
Plateau phase: have been suggested as source of preejaculatory emission of 2 or 3 drops of mucoid fluid; timing is essentially same as that of secretory activity of bartholin’s glands in female; active spermatozoa have been observed in this fluid.

 Lithium molybdenum disulphide battery cathode - Patent 4224390
The phase 2 region overlaps the plateau on which the phase 1 to phase 2 transition occurs in that cathode concentrations of lithium are observed in phase 2 equal to those observed during the transition from phase 1 to phase 2, but at voltages higher than that at which the transition occurred.
Phase 2 is a preferred phase of operation because of the excellent reversibility observed in batteries constructed with cathodes which have been conditioned to operate in phase 2.
In phase 3 operation, the cathode concentration of lithium may be decreased to overlap values of cathode lithium concentration found in phase 2 and in the plateau along which the phase 2 to phase 3 transition occurs.

 Action potential -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-11-06)
In the (Long nerve fiber that conducts away from the cell body of the neuron) axon fibers of (Any bundle of nerve fibers running to various organs and tissues of the body) nerves, depolarization results from the inward rush of sodium ions, while repolarization and hyperpolarization arise from an outward rush of potassium ions.
The depolarization phase of an action potential is due to the opening of voltage-gated ion channels, either sodium channels or calcium channels or a combination of both, depending on the particular membrane.
The repolarization phase of an action potential is due to the opening of voltage-gated potassium channels.

 Physiology of capnography
Phase II Consists of a rapid S-shaped upswing on the tracing (due to mixing of dead space gas with alveolar gas).
The slope of the phase III is dependent, therefore, on the emptying patterns of various alveoli with different V/Q ratios as well as continuous C0 excretion into the alveoli.
This represents the inspiratory phase during which the fresh gases (CO -free gases) are inhaled and CO concentration falls rapidly to zero.

Now coming to plateau phase, even though marked areolar engorgement develops late in the excitement phase, the areola become so tumescent with plateau-phase tensions that they impinge upon the erect nipples, creating an illusion that the responding woman partially has lost the nipple erection.
This ‘sweating’ phenomenon provides complete lubrication for the vaginal walls early in the excitement phase of the human female’s sexual response cycle and certainly is the first evidence of the vaginal barrel’s physiologic response to sexual stimulation.

 TECHNICAL MEMORANDUM 415: Plateau phase of cell cultures   (Site not responding. Last check: 2007-11-06)
Allan Savage, of the MeSH section, has pointed out that in the field of cell culture, there is a lag phase, followed by the log phase and the plateau phase.
MeSH will not create a main heading for plateau phase because it has relatively few postings and is also used in other contexts, particularly in relation to multiple myeloma.
In many cases plateau phase will be third tier, and need not be indexed, but if it is really important, use the 1996 term CELL CULTURE (probably NIM) with the appropriate cell line or cells being cultured.

An action potential is the local membrane potential created as a nerve impulse is transmitted.
Minimally, an action potential involves a depolarization, a repolarization and finally a hyperpolarization (or "undershoot").

 Plateau Potential
The original term "plateau potential" derived from the plateau phase in the action potential of the vertebrate heart (Wiedmann 1951).
Several additional physiological tests for plateaus were listed by Russell and Hartline (1982) based on their studies in lobster stomatogastric ganglion (see also Hartline and Graubard 1992 for more details).
Plateaus described to date derive from voltage-dependent inward current mechanisms that produce an "N"-shaped I(V) relation in the membrane.
