The trapezius muscles connect the head and arms to Base-Line support and are responsible for aligning the upper body.
The whole of both trapezius muscles should be free to fully extend in all directions.
Keeping it simple...
The left and right trapezius muscles are the superficial muscle layer from mid-back to the back of the head.
Big, thin muscles that curve down the neck and extend out towards each shoulder.
The trapezius muscles attach to the skull, shoulder blades, collar bones and the bones of the spine (via connective tissue).
Trapezius attachments to base of the skull.
Feel for the midline bump on the back of your head and then move your fingers towards your ears and feel the ridge where the trapezius muscles attach.
The midline bump is known as the external occipital protuberance one of the 5 midline markers for alignment.
Trapezius attachments to the spine.
The left and right trapezius muscles meet midline, attaching to the spine via the nuchal ligament in the back of the neck and the supraspinous ligament from the base of the neck down the back.
Attachments to the collar bones and shoulder blades.
Feel for all the bony bits where the trapezius attaches near the shoulder. A pencil-like bone at the front (the collar bone/clavicle) and lumps of bone at the shoulder and a ridge of bone at the back (parts of the shoulder blade/scapula).
The 3 parts of the trapezius.
The direction of the muscle fibres creates 3 sections in each trapezius: the lower, middle and upper trapezius.
Between the shoulder blades there is a diamond/ellipse shaped section of connective tissue extending from the muscle tissue.
Movement of the upper body should begin from the lower trapezius, extending upwards and out towards to the arms and head.
Think extension and expansion, like wings spreading wide.
The trapezius muscles - a blanket of muscle that should be smooth and wrinkle-free.
Look at the pictures, feel for the bony attachments and appreciate the shape and extent of your trapezius muscles.
There is a large potential for movement in the upper body but this area can also carry a lot of restrictions, causing tension, pain and body imbalance.
As you connect with your Base-Line and start to feel your alignment you will become more aware of the condition and range of movement in your upper body.
