Scapula

Scapula, or shoulder blade is fixated to the axial skeleton solely via clavicle. Motions of the shoulder blade, to a great extent, facilitate the movements of the upper arm.

Scapula in situ. Posterior oblique view.
Note the flat shape of the shoulder blade – in some parts of the supraspinous and infraspinous fossas, the thickness is less than 1 millimeter and looks semitranslucent when observed against the light.

Costal surface of the scapula
Anterior, or costal surface of the scapula.
The Latin term for that surface (facies subcostalis) may be misleading as "subcostal" mean "below rib" that corresponds to the scapula's location only in case the human is in the supine position.
