What is the long, straight shaft of a long bone called?

Explanation:
The diaphysis is the long, straight shaft of a long bone. It provides strength for weight bearing and is built mostly from compact bone. Inside it runs the medullary cavity, a hollow space that houses bone marrow. The ends of the bone are the epiphyses, with growth occurring near the junctions called metaphyses in developing bones.
