Trapezius - a muscle that can be responsible headache and shoulder problems.
π€·It has 3 parts to it:
Upper - elevates the pec girdle/elevates the shoulder - the shrugging movement.
Mid - retracts the scapula
Lower - depress the shoulders/scapula
It also works to extend the neck, side flexion of the neck, and assist in rotation of the upper thoracic region.
βοΈ Origin:
External occipital protuberance, nuchal ligament, spinous processes of C7 - T12.
βοΈ Insertion:
Lateral third of the clavicle, acromion, and spine of the scapula.
Itβs worth noting that the motor part of this muscle is actually controlled by Cranial Nerve XI. The ability to move the head freely is an important primal function for survival - for both finding of food and moving away from danger. Activities all cranial nerves have in common.
π The neck and upper back work we use in Bowen covers this group of muscles
very nicely.
πͺ Freedom of movement by the scapulae is very important for efficient shoulder function/arm movement.
π Tension in this muscle can lead to headaches due its connection to the occipital area, and may also cause restricted head movement.
Because this muscle is involved in thoracic rotation, a combination of this together with creating neck stiffness will add extra stress to the lumbar area and could well be a cause of lower back pain.
Sort the neck/head - sort the lower back.
