Your skeleton is divided into two systems — the axial and appendicular skeletons.

你的骨分为两个系统——轴向骨和附肢骨。

The appendicular skeleton is all the bones in your limbs, including your hands, arms, feet, and legs.

附肢骨是你四肢的所有骨，你的手、胳膊、脚和腿。

That's a lot of bones to keep tabs on, so anatomists often divide these structures first by location, into either axial or appendicular groups.

有很多骨头需要密切关注，所以解剖常首先根据位置将这些结构划分，分为轴向组或四肢组。

And it was worth it, because you learned about the basic structure of your skeletal system, including the arrangements of both the axial and the appendicular skeleton.

这是值得的，因为你了解了骨系统的基本结构，轴向和附肢骨的排列。

Now, the appendicular skeleton includes your upper and lower limb appendages and pectoral and pelvic girdles that attach to the axial skeleton at the shoulder and the thigh.

现在，附肢骨你的上肢和下肢附肢以及胸肌和骨盆带，它们附着在肩部和大腿的轴向骨上。

Now, if you managed to retain our introduction to human bones last week, you'll recall that anatomists typically divide the skeleton into two major parts: the axial and the appendicular.

现在，如果你还记得我们上周对人体骨的介绍，你会记得解剖常将骨分为两个主要部分：轴向和附肢。

The human skeleton is composed of both fused and individual bones supported by ligaments, tendons, muscles and cartilage. It is a complex structure with two distinct divisions. These are the axial skeleton and the appendicular skeleton.

人体骨由韧带、肌腱、肌肉和软骨支持的融合骨和独立骨组成。它是由两个不同部分组成的复杂结构，这两部分是中轴骨和附属骨。
