Question

Quizplus · Accepted Answer

Lifting of the periosteum disrupts blood vessels that enter bone through the periosteum, which deprives the underlying bone of its blood supply. This deprivation leads to necrosis and death of the area of infected bone, producing sequestrum, an area of devitalized bone. None of the other available options accurately identify the term "sequestrum".
