Cartilage is the strong flexible tissue connecting bones or joints in the body.

软骨是连接身体骨骼或关节的软组织。

The word " bone" can refer to an entire organ — like your femur or scapula — or just bone tissue.

" 骨" 这个词可以指代一整个器官，比如你的股骨或肩周骨，也可以仅仅指代骨组织。

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。

The arrangement of these bone tissues, though, can be slightly different, from one type of bone to the next.

然而，从一种骨骼到另一种骨骼，这些骨组织的排列可能会略有不同。

In the embryonic phase, bone tissue generally starts off as cartilage, which provides a framework for your bones to grow on.

在胚胎阶段，骨组织通常以软骨开始，软骨为骨骼的生长提供了框架。

In osteoid osteomas, the nidi are smaller than 1.5cm in diameter and are often surrounded by a ring of sclerotic bone tissue.

在骨样骨瘤中，癌巢直径通常小于1.5cm，并且通常被硬化的骨组织包围（边缘硬化）。

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。

It’s no surprise that heart tissue and bone tissue have really different jobs.

心脏组织和骨骼组织的工作完全不同也就不足为奇了。

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。

There is a continual exchange of calcium between blood serum and bone tissue.

血清和骨组织之间，钙持续交换。

When bone tissue is broken down like this, it changes the microscopic structure of the bone.

当骨组织像这样分解时，它会改变骨骼的微观结构。

Typically, fast-growing, active endotherms have a type of bone tissue called fibrolamellar bone.

通常，快速生长、活跃的吸热动物有一种叫做纤维板层骨的骨组织。

For example, as early as the 1960s, researchers began studying bone tissue.

例如，早在 1960 年代，研究人员就开始研究骨组织。

Likewise, osteoblasts are the blast cells of bone tissue, and the matrix they lay down is the nexus of calcium carbonate that forms your bone.

同样地，成骨细胞是骨组织的成骨细胞，它们形成的基质是形成骨骼的碳酸钙的结合体。

When the old bone tissue is cleaned out, the osteoclasts then undergo apoptosis, where they basically self-destruct before they can do any more damage.

当旧的骨组织被清除后，破骨细胞会发生凋亡，在造成更多伤害之前，它们基本上会自毁。

The artificial vertebra has a honeycomb structure, which allows the new bone tissue to grow into it, and surgical screws are not needed to attach it.

人工脊椎的蜂窝状结构允许新骨组织生长, 而且不需要手术螺钉。

Bone tissue is constantly being remodelled, meaning that bone is added or removed, depending on nutrient availability and the stress that the bone is under.

骨组织不断重塑，这意味着根据营养物质的可用性和骨骼所承受的压力，添加或移除骨骼。

But getting mixed results from bone tissue is not unheard-of: Fibrolamellar bone has been found in animals that we know are cold-blooded, like young alligators.

但是从骨组织中得到混合结果并非闻所未闻：在我们知道是冷血的动物身上发现了纤维板层骨，比如小鳄鱼。

Compact bone tissue on the other hand is quite dense, with no visible spaces. It forms the external layer of your bones and stores calcium for bone cells to use to make more tissue.

骨质致密，没有可见的空隙，形成骨骼的外层，储存钙，供骨细胞用来制造更多的组织。

If you went flying off the swings, a doctor would classify your broken arm as acute nociceptive pain because the pain was a result of damaged bone tissue and you likely won't have any pain after it heals.

如果你从秋千上掉下来，医生会把你的断臂归类为急性伤害性疼痛，因为这种疼痛是骨组织受损的结果，愈合后你可能不会有任何疼痛。
