Structurally speaking, you've got fibrous, cartilaginous, and synovial joints.

从结构上来说，你有纤维关、软骨关膜关。

Also, fibrillations form, essentially these cracks or clefts, on what used to be a smooth articular surface.

软骨纤维性颤动也将形成，其本质是这些原本十分光的软骨表面出现缝或口。

In addition to bones, there's cartilage and fibrous connective tissue that allows them to work together.

除了骨头，还有软骨纤维结缔组织才让它们得以一起工作。

Short, stiff hair, as on a brush. bristle. A piece of fiber that makes meat hard to chew. gristle.

• 短而硬的，子上的。硬。一块使肉难以咀嚼的纤维。软骨。

The trachea is kept open by 15-20 incomplete C-shaped rings of cartilage separated by fibrous connective tissue that stiffens the front and sides of the tube.

气管由15-20个不完整的C形软骨环保持打开状态，软骨环由纤维结缔组织分开，使前部侧面变硬。

So, the structural classification of your bones is all about what kind of material binds those bones together — like, is it a fibrous tissue or cartilage, or a special fluid-filled joint cavity.

所以，骨骼的结构分类就是关于是什么材料把这些骨骼结合在一起——比说，是纤维组织还是软骨，或者是一个特殊的充满液体的关腔。
