Lies between the diaphysis and epiphysis; it is a conical region adjacent to the area where active bone growth will occur.

The region between the shaft and the ends where growth occurs is the metaphysis. In a long bone, the diaphysis is the shaft and the epiphyses are the ends, with the metaphysis lying between them. This transitional, often conical zone lies adjacent to the area of active bone growth—the epiphyseal (growth) plate—where cartilage is replaced by bone during lengthening. That makes the metaphysis the site most closely associated with longitudinal growth, the process of endochondral ossification pushing the growth front toward the diaphysis as the bone lengthens. The other options describe different structures: the shaft, the ends, or the outer covering, none of which fit the described region.
