What's the difference between tetanic and tetanus?
Tetanic
Definition:
(a.) Of or pertaining to tetanus; having the character of tetanus; as, a tetanic state; tetanic contraction.
(a.) Producing, or tending to produce, tetanus, or tonic contraction of the muscles; as, a tetanic remedy. See Tetanic, n.
(n.) A substance (notably nux vomica, strychnine, and brucine) which, either as a remedy or a poison, acts primarily on the spinal cord, and which, when taken in comparatively large quantity, produces tetanic spasms or convulsions.

Tetanus
Definition:
(n.) A painful and usually fatal disease, resulting generally from a wound, and having as its principal symptom persistent spasm of the voluntary muscles. When the muscles of the lower jaw are affected, it is called locked-jaw, or lickjaw, and it takes various names from the various incurvations of the body resulting from the spasm.
(n.) That condition of a muscle in which it is in a state of continued vibratory contraction, as when stimulated by a series of induction shocks.
Example Sentences:
