Fig. 5From: Experimental determination of three-dimensional cervical joint mobility in the avian neckJoint angles for four cervical joints through time. In this trial, the neck was axially rotated from the cranial end over eight seconds. Joints are labeled according to the two cervical vertebrae they lie between, so C3-C4 corresponds to the motion measured between C3 and C4. Trace colors are red: axial rotation, green: lateral flexion, blue: dorsoventral flexionBack to article page
