A fissure or fracture running opposite to or crossing another fissure; in anatomy, a counteracting split or crack.
From Latin 'contra-' (against) + 'fissura' (fissure, split). Medical/anatomical term describing a secondary fissure that runs against the direction of an initial one.
Geologists and doctors use this term to describe cracks that form in response to stress from another direction—nature's way of creating even more complicated fracture patterns.
