080 A Review of the Shoulder Girdle

After learning about the bones of the shoulder girdle in previous episodes, let’s review and identify the different parts of the clavicle, scapula, and the proximal humerus based on what we’ve learned so far.


Transcript of Today’s Episode

Hello and welcome to another episode of Interactive Biology TV where we’re making Biology fun. My name is Leslie Samuel, and in this episode, I’m going to be doing a review of the shoulder girdle.

This is all review. This is all based on the videos that we’ve done up to this point dealing with the shoulder girdle. So, if you would like to review with me, and you would like to test yourself, what you can do is you can turn the volume down from the beginning and just answer as I point out the different structures.

Let’s get right into it.

First, we’re going to deal with the three bones of the shoulder girdle. The first bone is the clavicle, then, we have the scapula, and we have the proximal humerus.

Then, we spoke about the three joints. The three joints are: the sternoclavicular joint, the acromioclavicular joint, and the glenohumeral joint.

Now, let’s talk about the clavicle. With the clavicle, we have the acromial and the sternal end, and the shaft of the clavicle. Then, we have the deltiod tubercle. You can also see the deltoid tubercle over here, then we have the conoid tubercle, the trapezoid line, the subclavian groove, and the costal tuberosity.

Then, we spoke about the scapula. On the posterior aspect, you have the spine of the scapula, the acromion, or acromion process, the base of the spine of the scapule, the supraspinous fossa, the infraspinous fossa, the subscapular fossa, the glenoid fossa, and this is also the glenoid fossa.

Then, we have the coracoid process. We have the glenoid labrium with the glenoid ligaments. We have the infraglenoid tubercle, and up here, we have the supraglenoid tubercle. Lastly, we have the superior angle, the inferior angle, the lateral or glenoid angle along with the medial border, lateral border, and superior border.

Then, we move on to the proximal humerus where we have the head of the humerus, the anatomical neck of the humerus, the greater tubercle, the lesser tubercle, the deltiod tuberosity, the intertubercular groove or bicipital groove, the crest of the greater tubercle, or the lateral lip of the intertubercular groove. The superior, middle, and inferior facets of the greater tubercle.

Then, we spoke about the sternoclavicular joint, and the ligaments involved. We have the anterior sternoclavicular ligament and the posterior stenoclavicular ligament in the back. We have the interclavicular ligament and the costal clavicular ligament with the acromioclavicular joint, we have the superior acromioclavicular ligament and inferior acromioclavicular ligament.

Then, we have the trapezoid ligament, the conoid ligament, and the coracoclavicular ligament.

Lastly, we have the glenohumeral joint, and that is made up of the glenohumeral ligament which goes all around reinforcing the anterior and posterior part of the capsule. We have the coracohumeral ligament which is this ligament here, and we have the coracoacromial ligament and the transverse humeral ligament.

That’s pretty much it. I hope you were able to get all of that. Feel free to go over and over and over until you get it right. Quiz yourself. Turn the volume down so that, you can test yourself out, so that you can memorize all of those structures.

That’s it for this video. If you want more videos, more resources, more anything to help make Biology fun, head on over to the website, interactive-biology.com.

This is Leslie Samuel. That’s it for this video and I;ll see you in the next one.
