It mostly involves otic ganglion and stapes in which normal bone is replaced by spongy bones.

它主要累及耳神经节和镫骨，其中正常的骨被海绵骨取代。

The trabeculae are like a framework of beams that give structural support to the spongy bone.

骨小梁类似梁柱的构架，支撑起了松质骨的结构。

This spongy bone tissue is made up of tiny cross-hatching supports called trabeculae that help the bone resist stress.

这种海绵状骨组织由微小的交叉影线支撑物组成，称为小梁，帮助骨骼抵御压力。

Spongy bone is lighter and less dense.

海绵状骨更轻，密度更低。

In flat, short, and irregular bones, for example, these tissues kinda look like a spongy bone sandwich on compact-bone bread.

例如，在扁平、短和不规则的骨骼中，这些组织看起来有点像紧凑型骨面包上的海绵骨三明治。

They all have a dense, smooth-looking external layer of compact, or cortical bone around a porous, honeycomb-looking area of spongy bone.

它们都有致密、光滑的外层致密或皮质骨，围绕着多孔、蜂窝状的海绵骨区域。

Bones have two types of bone tissue; compact bone and spongy bone.

骨头有两种类型的骨组织；致密骨和海绵状骨。

Spongy bone tissue is typically found in the heads of long bones and in the inner layer of flat bones like the sternum.

海绵状骨组织通常存在于长骨的头部和胸骨等扁平骨骼的内层。

Some bones like the vertebrae, shoulder blades, and ribs consist mainly of spongy bone, so they are in great risk of fragility fractures.

有些骨骼，比如椎骨、肩胛骨和肋骨，主要是由松质骨构成，因此他们极易发生脆性骨折。

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.

骨质疏松症中，皮质骨会变薄、哈弗斯管变宽、松质骨内的骨小梁数目减少。

But in some of your classic long bones, like the femur and humerus, the spongy bone and its red marrow are concentrated at the tips.

但是在你的一些经典长骨中，比如股骨和肱骨，海绵状骨及其红色骨髓集中在尖端。

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，骨质疏松的异常包括松质骨中的骨小梁会减少，皮质骨变薄，还有哈弗斯管变宽。

Flat bones are generally thin and composed of two more or less parallel plates of compact bone enclosing a layer of spongy bone.

扁骨通常是菲薄的，由两层近似平行的密质骨骨板包绕一层松质骨组成。

But at least today we learned about the anatomy of the skeletal system, including the flat, short, and irregular bones, and their individual arrangements of compact and spongy bone.

但至少今天我们了解了骨骼系统的解剖学，包括扁平、短和不规则的骨骼，以及它们紧凑和海绵状骨骼的个体排列。

Looking at a cross-section of a bone, there's a hard-external layer known as the cortical bone and a softer internal layer of spongy bone or trabecular bone that is composed of trabeculae.

来看一根骨头的横截面，这个硬质的外层叫皮质骨，而软一些的松质骨内层，由骨小梁构成。

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。
