burn

Pronunciation: bern

Definition:

1. A sensation of pain caused by excessive heat, or similar pain from any cause.
2. A lesion caused by heat or any cauterizing agent, including friction, caustic agents, electricity, or electromagnetic energy; types of burns resulting from different agents are relatively specific and diagnostic. The division of burns into three levels (superficial, partial thickness, full-thickness, [q.v.]) reflects the severity of skin damage (erythema, blisters, charring, respectively).
