WebChronaxie definition: The minimum time necessary to excite a tissue, such as that of muscle or nerve cells, with an electric current of twice the rheobase. WebMuscle denervation in a patient is suggested by signs of muscle weakness, wasting (i.e., atrophy), and fasciculations, in muscles innervated by the nerve or root in question. Clinical evidence of muscle denervation indicates damage to the lower motor neurons innervating that muscle anywhere from the level of the cell body to the peripheral ...

Chronaxies - definition of chronaxies by The Free Dictionary

Webchro·nax·ie ( krō'nak-sē ), A measurement of excitability of nervous or muscular tissue; the shortest duration of an effective electrical stimulus having a strength equal to twice the minimum strength required for excitation. Synonym (s): chronaxia, chronaxis, chronaxy [G. chronos, time, + axia, value] Webn. pl. chro·nax·ies. The minimum interval of time necessary to electrically stimulate a muscle or nerve fiber, using twice the minimum current needed to elicit a threshold response. [French : Greek khronos, time + Greek axiā, value (from axios, worthy; see ag- in Indo-European roots ).] WebChronaxie (c) is the Lapicque descriptor of the stimulus pulse duration for a current of twice rheobasic (b) strength, which is the threshold current for an infinitely long-duration stimulus pulse. Lapicque showed that these two quantities (c,b) define the strength-duration curve for current: I = b (1+c/d), where d is the pulse duration. canon bci 16 color ink tank
