Abrasion collar
Abrasion Collar
Abrasion collar (pronunciation: /əˈbreɪʒən ˈkɒlər/) is a term used in forensic pathology to describe a specific pattern of abrasion seen around a gunshot wound.
Etymology
The term "abrasion collar" is derived from the English words "abrasion", meaning the process of scraping or wearing away, and "collar", referring to something that encircles or bestows. In the context of forensic pathology, it refers to the ring of abrasion that encircles a gunshot wound.
Definition
An abrasion collar is a ring of abraded skin that surrounds a gunshot wound of entrance. It is caused by the bullet scraping the skin as it penetrates, causing a rim of abrasion. The presence of an abrasion collar can help forensic pathologists determine the direction of the bullet's path.
