Medical Definition of ANODE

1

: the electrode of an electrochemical cell at which oxidation occurs: as a : the positive terminal of an electrolytic cell b : the negative terminal of a storage battery that is delivering current

2

: the electron-collecting electrode of an electron tube—compare cathode

anode

noun    (Concise Encyclopedia)

Terminal or electrode from which electrons leave a system. In a battery or other source of direct current, the anode is the negative terminal. In a passive load it is the positive terminal. In an electron tube, electrons from the cathode travel across the tube toward the anode; in an electroplating cell, negative ions are deposited at the anode.
