Pectoral Girdle Consists of: 1) clavicle (anterior): convex forward & concave lateral. Important structures: a) acromial end: articulates with scapula b) sternal end: attaches to sternum c) conoid tubercle: ligament attachment site

Pectoral Girdle (cont) 2) scapula (posterior): acromion superior & lateral. Important structures: a) spine: extends into the acromion b) acromion: connects with clavicle c) coracoid process: muscle attachment d) glenoid cavity: socket for humerus e) suprascapular notch: passage for nerves f) superior, lateral and medial borders g) supraspinous fossa
