Shoulder girdle: Bones and location

组成肩胛带的骨及肩胛带的位置

The shoulder girdle is made up of two bones – the clavicle and the scapula. Let’s go on to look at these bones in a little more detail.

肩胛带由锁骨和肩胛骨两块骨组成。我们继续来更详细地观察这些骨。

So, as I just said, the clavicle is one of the bones of the shoulder girdle. This long bone articulates with the acromion of the scapula forming the acromioclavicular joint which you can now see highlighted in green. The acromioclavicular joint is also known simply as the AC joint.

如刚才所述，锁骨是组成肩胛带的两块骨之一。锁骨是块长骨，与肩胛骨肩峰形成肩锁关节，如绿色区域所示。肩锁关节也简称为 AC 关节。

Now, let's look at the scapula. This bone is a fat, triangular bone – also known as the shoulder blade and is located posterior to the rib cage.

现在，我们来看肩胛骨。肩胛骨是块三角形扁骨，也被称为琵琶骨，位于胸廓后侧。

Let's talk about some key features of the scapula starting with the acromion.

我们来讨论一下肩胛骨的一些关键特征，首先是肩峰。

If we change perspective so that we have a posterior view of the scapula and zoom in slightly, we can see how the acromion of the scapula articulates with the clavicle to form the acromioclavicular joint.

如果我们转换视角，可以看到肩胛骨的后视图，稍微放大，我们可以看到肩胛骨肩峰是如何与锁骨形成肩锁关节的。

Another feature of the scapula that we'll look at is the coracoid process. Let's see what the structure looks like on our anterior view of the skeleton.

我们将介绍的肩胛骨的另一个特征是喙突。我们来看一下肩胛骨的前视图。

You can see that it's a hook-like bony projection and that it's situated superior to the glenoid cavity. The head of the humerus articulates with the glenoid cavity to form the shoulder joint.

我们可以看到，喙突是一种钩状的骨突起，位于关节盂上部。肱骨头与关节盂形成肩关节。

To see the last feature of the scapula that we're going to talk about, we need to flip our skeleton.

要介绍肩胛骨的最后一个特征，我们需要翻转这块骨。

The spine of the scapula is a protruding bony ridge on the posterior surface of the scapula that is easily palpable and separates the superior spinous fossa from the inferior spinous fossa.

肩胛棘是肩胛骨后表面上的一种突出的骨嵴，很容易触及，它将棘上窝与棘下窝分开。
