The trapezius muscles connect the upper body to the core support provided by the Base-Line muscles.
The whole of both trapezius muscles should be free to fully extend in all directions, without pain or tension, guiding the head and arms through a full range of natural movement and aligning the upper body.
Keeping it simple...
The left and right trapezius muscles form the most superficial muscle layer from the back of the head to mid-back.
They are big, thin muscles, curving down the neck and extending out towards each shoulder.
Multiple connective tissue structures connect these muscles to the bones of the spine, shoulder and skull.
Look at the pictures, feel for the bony attachments and appreciate the shape and extent of your trapezius muscles.
What condition are they in?
There is a large potential for movement in the upper body but this area can also carry a lot of restrictions that reduce the range of movement possible, causing tension, pain and imbalance.
The trapezius muscles attach to the base of skull.
Feel for the midline bump on the back of your head and then move your fingers towards your ears to 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.
The left and right trapezius muscles merge midline with the nuchal ligament in the back of the neck.
The trapezius muscles attach to the collar bone and shoulder blade of each arm.
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 left and right trapezius muscles meet midline merging with the supraspinous ligament from the base of the neck to level with the bottom ribs.
Each trapezius can be split into 3 sections: 2 triangles (upper and lower trapezius) and a horizontal strip from midline to the shoulders (middle trapezius).
Connective tissue connects the trapezius muscles to the skull, shoulder blades and collar bones.
Between the shoulder blades there is also connective tissue, forming a diamond/ellipse shape.
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.
