3.1 Classification and Medico-Legal Significance of Injuries

The injury's classification (the exam's menu): 1. By the causative agent: mechanical (the blunt-and-sharp; the firearms); thermal (the burns- and-scalds; the hypothermia); electrical; chemical (the corrosives); radiation. 2. The mechanical's own classes: the abrasion (the surface's scrape — the direction's evidence), the bruise/contusion (the bleeding-under-skin — the age's colour changes: the famous spectrum), the laceration (the tear), the incised wound (the cut), the stab (the penetration), the firearm wounds (the LAW5510-U10 depth). 3. By the legal classification: simple vs grievous (the Criminal Code's categories: the dangerous-to-life, the permanent injury, the fractures — the punishment's grading). The medico-legal significance: the weapon's inference (the wound's shape — the blunt-vs- sharp); the force's assessment; the direction-and-angle (the assault's reconstruction); the age (the injuries' timing — the fresh-vs-old: the abuse's history); the vitality (the before-vs-after- death: the vital reaction's presence); the self-defence's patterns (the defensive injuries — the victim's raised arms); the suicide-vs-homicide's signs (the hesitation marks vs the multiple- angled wounds).
