Show Stretching, Bending Spine Movements
In addition to the realistic movement afforded by the flexibility of this skeleton, all the bones on the right half have been enhanced with numbercoded, hand-painted muscle origins in red and insertions in navy blue. Additional colors differentiate the components of the erector spinae muscle complex from other muscle origins and insertions of the neck and back regions. The ilicostalis features origins in orange and insertions in yellow; the longissimus is detailed in dark green origins and light green insertions. On the left half of the skeleton, all bones and osteological features of anatomical and clinical significance have also been number-coded for identification. A comprehensive key to all coded structures is furnished.
