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

在骺之间的是长干。

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

骺与干交界的区域叫做干骺。

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，骺与干之间还有一狭窄的部分，称为干骺。

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骺，比如股远与胫近。

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，由两块骺（即它的两）和间的干（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.

现在，从解剖学角度，观察一长，比如股，它有两骺，位于骼两，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，或称骺，包围着干，或干，干的心不是海绵状，而是包围着一充满黄色髓的空心髓腔。
