Bones

Clavicle: with sternal and acromial ends

Double-curved long bone

Sternal end articulates with manubrium of sternum

Acromial end articulates with acromion

Osteological features

Deltoid tubercle for attachment of the deltoid muscle

Conoid tubercle for attachment of conoid ligament

Subclavian groove for attachment of subclavius muscle

Trapezoid line where trapezoid ligament attaches

Serves as a strut suspending the scapula and limb with maximum freedom

Scapula: lying against posterolateral thorax

Triangular flat bone

Lies posterolateral on second through seventh ribs

Osteological features

Concave costal surface = subscapular fossa

Posterior surface divided by spine = transverse ridge of bone

Supraspinous fossa

Infraspinous fossa

Acromion = flattened lateral end of spine

Coracoid process = anterior projection above glenoid cavity

Glenoid cavity = socket for head of humerus

Suprascapular notch (scapular notch) = notch found on superior border, two thirds of the way along laterally

Capable of considerable movement over thoracic wall
