1. infectious disease which usually enters the body through wounds. tetanus\tet"a*nus\ , n. [l., fr. gr. , fr. stretched, to stretch.].
2. (med.) 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.
3. (physiol.) 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.tetanus n.
4. an acute and serious infection of the central nervous system caused by bacterial infection of open wounds; spasms of the jaw and laryngeal muscles may occur during the late stages [syn: lockjaw].
5. a sustained muscular contraction resulting from a rapid series of nerve impulses.

9. Tetanus is a serious painful disease caused by bacteria getting into wounds. It makes your muscles, especially your jaw muscles, go stiff. a serious illness caused by bacteria that enter your body through cuts and wounds and make your muscles, especially your jaw, go stiff = lockjaw (tetanos, from tetanos ). or lockjaw Acute bacterial disease caused by Clostridium tetani (see:
clostridium). Spores of this organism are common, especially in soil; it thrives away from oxygen in deep wounds, especially punctures. Its toxin stimulates nerves, causing muscle rigidity with frequent spasms. This may occur around the site of the wound or, if the toxin reaches spinal motor ganglia via the bloodstream, throughout the body. The jaw muscles are almost always involved (lockjaw). Vaccination every few years is the best protection; an antitoxin prevents or delays symptoms in cases of suspect wounds but has limited value once they develop. Treatment usually includes antibiotics, sedatives, and muscle relaxants. Recovered patients are not immune.
