Chronaxie definition
Webchronaxie ( ˈkrəʊnæksɪ) or chronaxy n (Physiology) physiol the minimum time required for excitation of a nerve or muscle when the stimulus is double the minimum (threshold) necessary to elicit a basic response. Compare rheobase [C20: from French, from chrono- + Greek axia worth, from axios worthy, of equal weight] Webchron (krŏn) n. 1. The interval of time represented by a specific stratum of rock selected to be representative of all rocks formed during the same span of time. 2. The interval of time between two reversals of the Earth's magnetic polarity. [From Greek khronos, time .] American Heritage® Dictionary of the English Language, Fifth Edition.
