Document Summary

Muscles of the pectoral girdle: separated into 2 groups, 1. Muscles that move the shoulder girdle (includes the clavicle and/or the scapula: anterior, posterior, 2. Pectoral girdle: posterior (move the shoulder girdle, trapezius (2) Insertion point for traps are the spine of the scapula. Origin is the ligamentum nuchae and nuchal ine. Superior fibres (up near the neck, running down the base of the skull: responsible for upward rotation of the scapula. If the entire scapula shifts upwards, its called elevation. If it shifts away from the spine, abduction: depression is if scapula shifts downwards. If inferior angle swings closer to the spine, called downward rotation: moving toward the spine, adduction of the scapula. Nuchal line: attachment for the ligamentum nuchae line. Inferior fibres: run from the inferior thoracic region to the very end of the medial portion of the spine of the scapula, causes upwards rotation of the scapula.
