Quizplus · Accepted Answer

The correct order is 1, 3, 2, 5, 4. Extensive bleeding occurs (1) followed by the formation of a hematoma to close off blood flow (3). An internal callus then forms from a network of spongy bone (2) and osteoblasts then replace the central cartilage of the callus (5). Finally, remodeling occurs by osteoblasts and osteoclasts leaving little evidence of the break (4). Choice B follows the correct sequence of events.
