Document Summary

Transverse part: broad appneurosis at the level of t1-t4 spinous processes. Ascending part: superior rotation of scapula depress the scapula tilts the scapula posteriorly. Transverse part: retracts the scapula prevents winging of the scapula. Innervation: cranial nerve xi (accessory nerve) and cervical plexuss (c2-c4) Insertion: medial border of the scapula (below the scapular line) Action: inferior rotation of the scapula retracts the scapula prevents winging of the scapula. Action: inferior rotation of the scapula protracts the scapula assists respiration when the scapula is fixed tilts the scapula anteriorly. 3) inferior part (inferior angle and medial border) Lower fibres: superior rotation of scapula prevents winging of the scapula tilts the scapula posteriorly assists respiration when scapula is fixed. Action: inferior rotation of the scapula elevates the scapula inclines the neck towards the same side when scapula is fixed. 1. 10 b: the sternoclavicular joint and its ligaments (pg. Muscles of the shoulder girdle and joint (pg.
