On imaging, the mass is typically within the medullary cavity.

在影，块通常位于腔内。

Bit by bit, it's all stored in her bones...specifically, medullary bone.

一点一点地，储在骨头里，确切地说，在骨里。

Medullary bone is very special bone that's laid down only by an ovulating female.

骨是一种很独特的骨头，只有排卵期的雌性恐龙才有。

And like a Sauroposeidon, she'll store that calcium in her medullary bone.

就波塞冬龙一样，她会把钙储在骨。

Medullary is a layer of bone which lines the interior of leg bones. It has no structural purpose.

骨是排列在腿骨的内部的一层骨头。它没有结构的用途。

Once stored in medullary bone, calcium and minerals can easily be broken down and sent to where it's needed.

一旦贮在骨里钙和矿物很容易被分解，并且被输送到需要它的地方。

But since it could have been used to store medullary bone, we think that the repetisaurus this osteoderm came from was female.

但由于它可能被用来储骨，我们认为这种骨皮来自的重复龙是雌性的。

This ends up causing new bone formation and the medullary cavites of the skull can expand outward, which causes enlarged cheeks and a " hair-on-end" appearance on skull x-ray.

这最终导致新骨形成，及颅骨腔可能向外扩展，在头颅X线表现为增大的脸颊以及“竖发征”。

Of course, the technique is not foolproof, as only female dinosaurs that are preparing to lay eggs, not juveniles or ones that just recently laid eggs, show medullary bone.

当然，这项技术并非万无一失，因为只有准备产卵的雌性恐龙，而不是幼龙或刚刚产卵的恐龙，才会显示出骨。

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的空心腔。

Another part of this study also showed that the fossils of those brooding dinosaurs didn't have medullary bone, a type of bone tissue found in ovulating female birds that remains for a short time after they lay their eggs.

这项研究的另一部分还表明，那些育雏恐龙的化石没有骨，骨是一种在排卵的雌性鸟类中发现的骨组织，在它们产卵后会保留很短的时间。
