current

current (ker´rent)

A stream or flow of fluid, air, or electricity. [L. currens, pres. p. of curro, to run]
action c. an electrical c. induced in muscle fibers when they are effectively stimulated; normally it is followed by contraction.
after-c. See aftercurrent.
alternating c. (AC) a c. that flows first in one direction then in the other; e.g., 60-cycle c.
anodal c. a c. produced in tissues under the anode when the circuit is closed.
ascending c. the direction of c. flow in a nerve when the anode is placed peripheral to the cathode, in contrast to descending c.; the convention used is that c. flows from positive to negative.centripetal c;
axial c. the central rapidly moving portion of the bloodstream in an artery.
centrifugal c. descending c
centripetal c. ascending c
d'Arsonval c. high frequency c
demarcation c. c. of injury
descending c. the direction of c. flow in a nerve when the cathode is placed peripheral to the anode, in contrast to ascending c.centrifugal c;
direct c. (DC) a c. that flows only in one direction; e.g., that derived from a battery; sometimes referred to as galvanic c. See also galvanism.
electrotonic c. See electrotonus.
galvanic c. See direct c., galvanism (1).
high frequency c. an alternating electric c. having a frequency of 10,000 or more per second; it produces no muscular contractions and does not affect the sensory nerves.d'Arsonval c., Tesla c;
c. of injury the c. set up when an injured part of a nerve, muscle, or other excitable tissue is connected through a conductor with the uninjured region; the injured tissue is negative to the uninjured.demarcation c;
labile c. an electrical c. applied to the body by means of electrodes that are constantly shifted about.
Tesla c. high frequency c
