If you can’t get your head around the movements that occur at the shoulder girdle, this video and blog will clearly explain it. This is everything you need to know about the shoulder girdle and movements for your Level 2 or 3 Anatomy and physiology Exam
- The difference between the Shoulder Joint and the Shoulder Girdle
- Why you need to know about the shoulder girdle actions
- All 4 movements that occur at the shoulder girdle, with clear actions you can follow along.
- Three Example Mock Questions to test your knowledge
2 reasons you need to know about the shoulder girdle actions:
Firstly you need to know the four actions of the shoulder girdle to prepare for your L2 or L3 anatomy and physiology exam.
You can expect 5-8 questions that relate to joint actions and joint types. This includes knowing the difference between the shoulder girdle and the shoulder joint.
Secondly, you need to know this information when planning and coaching your clients. Understanding the actions that occur at each joint it allows you to know what you are looking for when your client is doing the exercise.
Let’s take the press up as an example. During the downward phase of a press-up the client’s scapula should retract, and then in the upward phase, the scapula will protract again.
Many clients put unnecessary strain on their rotator cuff muscles by moving more from the shoulder joint (the ball and socket) than the shoulder girdle. This can cause injury, but also leads to ineffective recruitment of the target muscle.
Shoulder Girdle or Shoulder Joint
There is a difference between the Shoulder Girdle and the Shoulder Joint, and you need to know this ready for your exam and when working with clients.
The Shoulder girdle is made up of the Scapula (shoulder blades) and Clavicle (collar bone)
However the Shoulder Joint is the ball and socket joint where the humerus articulates within the glenohumeral socket. This is the joint we are investigating in today’s video training.

What are the 4 actions at the shoulder girdle?
Here’s a summary of all 4 movements that occur at the shoulder girdle, alongside the muscle that creates this when contracting concentrically.
Notice there are 2 paired actions:
Elevation: created by the Upper fibres of the trapezius and levator scapulae
Depression: created by the Lower fibres of the trapezius
Retraction: created by the rhomboids and mid fibres of trapezius
Protraction: created by the serratus anterior and pectoralis major and minor
