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

你的骨骼分为两个系统——轴向骨骼附肢骨骼。

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

附肢骨骼是你四肢的所有骨骼，包括你的手、胳膊、。

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.

有很多骨头需要注，所以解剖学家通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，因为你了解了骨骼系统的基本结构，包括轴向附肢骨骼的排列。

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，附肢骨骼包括你的上肢下肢附肢以及胸肌骨盆带，它们附着在肩部大的轴向骨骼上。

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的介绍，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.

人体骨骼由韧带、肌腱、肌肉软骨支持的融合骨独立骨骼组成。它是由两个不同部分组成的复杂结构，这两部分是中轴骨附属骨。
