Tetany
Definition:
(n.) A morbid condition resembling tetanus, but distinguished from it by being less severe and having intermittent spasms.
Example Sentences:
(1) It is shown from an analysis of the transient force responses observed after sudden changes in muscle length applied both at full and reduced overlap and during the rising phase of short tetani that these responses can be explained on the basis of varying numbers of cross bridges attached at the time of the length step.
