The contraction bands of cardiac and skeletal muscle probes were studied. They were taken from autopsy cases with different death causes. The morphologic characteristics of the contraction bands that were closely related to diagnosis were carefully observed. It was found that the morphological patterns of the contraction bands were various and some were regularly seen for the death with certain causes. The forensic significance of the contraction bands was then discussed and it was suggested that the morphology of contraction bands of the striated muscle correlate to the type and structure of tissues as well as to the property of injuries.
