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

在哈弗斯管周围有许多同心薄片，看起来有点像树年轮。

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

在这些骨单位心，这个部分被称作哈弗斯管，供了为骨细胞供应血神经支配间。

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.

骨质疏松症，皮质骨会变薄、哈弗斯管变宽、松质骨内骨小梁数目减少。

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，骨质疏松异常包括松质骨骨小梁会减少，皮质骨变薄，还有哈弗斯管变宽。

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.

它也散布着被称为哈弗斯运河特征，这是血管为快速生长组织带来营养所遵循途径。
