| law of polar excitation | A given segment of a nerve is irritated by the development of catelectrotonus and the disappearance of anelectrotonus, but the reverse does not hold; i.e., excitation occurs at the cathode when the circuit is closed and at the anode when it is opened. Synonym: Pfluger's law. (05 Mar 2000) |

| area under curve | A statistical means of summarizing information from a series of measurements on one individual. It is frequently used in clinical pharmacology where the auc from serum levels can be interpreted as the total uptake of whatever has been administered. As a plot of the concentration of a drug against time, after a single dose of medicine, producing a standard shape curve, it is a means of comparing the bioavailability of the same drug made by different companies. (12 Dec 1998) |
| area under the curve | A measure of how much of a drug reaches the bloodstream in a set period of time, usually 24 hours. AUC is calculated by plotting drug blood concentration at various times during a 24-hour or longer period and then measuring the area under the curve between 0 and 24 hours as shown in the figure to the right. (09 Oct 1997) |
| Barnes' curve | A curve corresponding in general with Carus' curve, being the segment of a circle whose centre is the promontory of the sacrum. (05 Mar 2000) |
