Document Summary
Articulation and associated structures (ligaments or bursae) Sterno-angle/manubriosternal joint: joint between the manubrium and the body: used to make reference to other thoracic structures. One end of the clavicle is round: sternal end, which articulates with the manubrium of the sternum. Other end is flattened: acromial end, which articulates with the scapula. In the posterior view there are these bony landmarks: Spine of scapula: divides the posterior surface into, supraspinous fossa. Acromion process the end of the spine of the scapula. Lateral/axillary border: small indentation through which the suprascapular neurovascular bundle will gain access to the posterior structures of the scapula. Two features of the scapula that are not labeled in the image are: Super-glenoid tubercle (above the glenoid tubercle: site of attachment for the long head of the biceps. Infer-glenoid tubercle (below the glenoid tubercle: site of attachment for the long head of the triceps. Both are enlargements on either pole of the glenoid cavity.
