Between the two epiphyses, is the diaphysis, also called the bone shaft.

在骨骺之间的是长骨骨干。

Between each epiphysis and the diaphysis, there's a region called the metaphysis.

骨骺与骨干交界的区域叫做干骺端。

In children and adolescents, there is an additional narrow portion between the epiphysis and the diaphysis called the metaphysis.

在儿童和青少年中，骨骺与骨干之间还有一个狭窄的部分，称为干骺端。

In comparison, osteoid osteomas typically affect the diaphysis of long bones like the tibia, and don't usually erode the surrounding bone.

相比之下，骨样骨瘤通常影响长骨骨干，例如胫骨，并且一般不侵蚀周围骨骼。

Now, long bones, like the femur, are made up of two epiphyses, which are its ends, and the diaphysis, which is the shaft.

长骨，例如股骨，由两块骨骺（即它的两端）和中间的骨干（即杆状的部分）组成。

These flared ends, or epiphyses bookend the bone's shaft, or diaphysis, which — instead of having spongy bone in the center — surrounds a hollow medullary cavity that's full of that yellow marrow.

这些张开的末端，或称骨骺，包围着骨干，或骨干，骨干的中心不是海绵状骨，而是包围着一个充满黄色骨髓的空心髓腔。
