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

你骨骼分为两个系统——轴向骨骼和附骨骼。

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

附骨骼是你所有骨骼，包括你手、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，所以解剖学家通常首先置将这些结构划分，分为轴向组或组。

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，因为你了解了骨骼系统基本结构，包括轴向和附骨骼排列。

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，附骨骼包括你上和下附以及胸肌和骨盆带，它们附着在肩部和大腿轴向骨骼上。

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骼介绍，你会记得解剖学家通常将骨骼分为两个主要部分：轴向和附。

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.

人体骨骼由韧带、肌腱、肌肉和软骨支持融合骨和独立骨骼组成。它是由两个不同部分组成复杂结构，这两部分是中轴骨和附属骨。
