Around the Haversian canals, there are concentric lamellae, which look a bit like tree rings.

弗斯管周围有许多同心薄片，看起来有点像树的年轮。

What we see here is the beginning of dense haversian bone.

我们看到的是致密佛的开始。

In the center of these osteons, there are hollow spaces called Haversian canals, which contain the blood supply and innervation for the bone cells.

些单位的中心，个中空的部分被称作弗斯管，提供了为细胞供应血液以及神经支配的空间。

In osteoporosis, there's thinning of the cortical bone, widening of the Haversian canals and a decrease in the number of trabeculae in the spongy bone.

质疏松症中，皮质薄、弗斯管宽、松质内的小梁数目减少。

It's also dotted with features known as Haversian canals, which are the pathways the blood vessels followed to bring nutrients to the fast-growing tissue.

它也散布着被称为弗斯运河的特征，是血管为快速生长的组织带来营养所遵循的途径。

So with osteoporosis, abnormal findings include fewer trabeculae in the spongy bone and thinning of the cortical bone, as well as the widening of the Haversian canals.

那么，质疏松的异常包括松质中的小梁减少，皮质薄，还有弗斯管宽。

We know we begin with calcified cartilage that will form into primary bone and then mature into secondary bone and then eventually develop into something called dense haversian bone.

我们知道我们从钙化软开始，它形成初级，然后成熟为次级，最后发展成一种叫做致密弗斯的东西。
