Zoomify Images: Fig 09-20 Human vs. cow scapula: posterior/lateral views

Fig 09-20 A human left scapula (posterior view) is compared to a cow’s left scapula (lateral view). The acromion process is well developed in humans (arrow); it is very small in the cow and other ruminant artiodactyls. The greatest length of the cow’s scapula (and the scapulas of most other mammals) extends from the glenoid cavity to the dorsal border (parallel to the scapular spine). This is not the case in humans, where the greatest length lies between the superior and inferior borders.
