Pelvic girdle
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

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
