HN210 Lecture Notes - Lecture 2: Subacromial Bursa, Coracoclavicular Ligament, Glenoid Cavity
Document Summary
Includes pectoral, scapular and lateral supraclavicular regions: 3 joints that make up the shoulder complex. Clavicle at the sternum allows for elevation and rotation. Most anterior part of the shoulder gridle. Inferior side of the clavicle is rough allowing for muscle attachment. Sternal end is more rounded like a ball. Towards the acromial end it starts to flatten and rise up to allow for articulation in the acromial. Clavicle is the only think that joins the upper limb to the axial (axial skeleton is closer to the midline) Spine of the scapula (posterior surface) divides the superior part of the scapula to the inferior parts. Scapula moves along the ribs, protraction, retraction, rotation etc. Able to do this because it has a lot of muscles that allow for movement. Only posterior view you can see the spine. During a separated shoulder the ac joint is affected because the bones are separated.
