Quizplus · Accepted Answer

Coup and contrecoup injuries are caused by the brain moving within the skull, which can be influenced by the involvement of cerebrospinal fluid (A), the lag of the brain and the disproportionate distribution of cerebrospinal fluid during rapid head movements (B), and whether the head was moving prior to impact (C). These factors contribute to the brain striking the interior of the skull at the site of impact (coup injury) and on the opposite side (contrecoup injury).
