Quizplus · Accepted Answer

Located between the cortical plate and the cribriform plate is a layer of spongy or cancellous bone. The cribriform plate, also called the alveolar bone proper, is the bone that forms the socket. Radiographically it is referred to as the lamina dura. The cortical plate is a layer of compact bone on the buccal or lingual surface.
