From: Three-dimensional kinematic analysis of the pectoral girdle during upside-down locomotion of two-toed sloths (Choloepus didactylus, Linné 1758)

Figure 4

Mean 3D kinematics of the pectoral girdle over a step cycle (n = 20). A: 1st thoracic vertebra; B: scapular center of rotation/scapula; C: shoulder joint/humerus; D: sterno-clavicular joint/clavicle. Translations shown left, rotations right. Translations and rotations about x-axes are red, translations about y-axes are green, translations and rotations about z-axes are blue. The anatomical significance of these motions is detailed in Table 3 and Fig. 2.
