Shoulder Girdle
consists of two bones:
clavicle & scapula
is the largest & longest bone of the upper limb. lenght on adult equals approx. 1/5 of the body height. Humerus articulates with the scapula.
Parts of Shoulder Girdle
1. Surgical neck: tapered area below the head & tubercles. Site of frequent fractures requiring surgery

2. Anatomic neck: appears as a line of demarcation between the rounded head and the adjoining greater and lesser tubercle.

3.Lesser Tubercle: below the anatomic neck on the anterior surface.

4. Greater Tubercle: lateral process and the pectoralis major and supraspinatus muscles attach.

5. Clavicle - collarbone w/double curvature have 3 main parts. Articulates w/lateral or acromia extremity (end) of the clavicle articulates with the acromion of the scapula. This joint or articulation is clld acromioclavicular.
