Figure 5. Right scapulocoracoid and humerus of Struthio camelus showing osteological features and muscle origins (shaded) and insertions (unshaded). Scapulocoracoid in lateral (A) and medial (B) views, and humerus in ventral (C) and dorsal (D) views. Not drawn to scale. Dorsomedial curvature of the scapulocoracoid is removed. In A, the insertion of the M. pectoralis is onto the Ligamentum sternocoracoideum laterale. Lower-case abbreviations are skeletal elements, upper-case abbreviations are muscles.
