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。

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。

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

骨巨细胞瘤通常位于长骨骨骺，比如股骨远端与胫骨近端。

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，观察一个长骨，比如股骨，它有两个骨骺，位于骨骼两端，与其他骨骼共同形成关节。

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。
