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

从结构上来说，你有纤维关、软关和滑膜关。

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

软纤维性颤动也将形成，其本质这些原本十分光滑的软表面出现缝或口。

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，骼的结构分类就关于什么材料把这些骼结合在一起——比如说，纤维组软，或者一个特殊的充满液体的关腔。

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

除了头，有软和纤维结缔组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.

• 短而硬的毛，如刷子上的。硬毛。一块使肉难以咀嚼的纤维。软。

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形软环保持打开状态，软环由纤维结缔组分开，使前部和侧面变硬。
