 tension] . Relating to or of the nature of electrotonus.

 nerve produced when in the electrotonic state. 



Electrotonus (e-lek-trof -o-nus) \if/xKrpov, amber; 

 tovoc, tension]. The change of condition in a nerve 

 during the application of a current of electricity. A 

 decrease in the electro-motive force of a nerve, effected 

 by sending a current through the nerve in the opposite 

 direction to the nerve-current, is termed the negative 

 phase of electrotonus, while an increase in the electro- 

 motive force of a nerve, effected by sending a current 

 through a nerve in the same direction as the nerve- 

 current, is termed the positive phase of electrotonus.

 E., Unguent. (B. P.), elemi and simple ointment; it 

 is used as an application to indolent sores and boils.

 is most common in the leg and genitals. E. grae- 

 corum. See Leprosy. E. indica. Synonym of
