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

之间的是长干。

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

与干交界的区域叫做干端。

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

儿童和青少年中，与干之间还有一狭窄的部分，称为干端。

The giant cell tumor typically arises in the epiphysis of the long bones, like the distal femur and the proximal tibia.

巨细胞瘤通常位于长，比如股远端与胫近端。

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

长，例如股，由（即它的端）和中间的干（即杆状的部分）组成。

Now, in terms of anatomy, looking at a long-bone like the femur - it has two epiphyses, which are the ends that contribute to joints with other bones.

现，从解剖学角度，观察一长，比如股，它有，位于骼端，与其他骼共同形成关节。

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，包围着干，或干，干的中心不是海绵状，而是包围着一充满黄色髓的空心髓腔。
