Anatomical model of the human spine made up of individual vertebrae and three alignment jigs. Each vertebra shows its own code (from T1 to T12 and from L1 to L5) and is designed to be threaded onto the corresponding jig, so as to form a straight and orderly spine. Once assembled, it reproduces the sequence of the thoracic and lumbar vertebrae with the spinous and transverse processes. Suitable as a visual aid for studying anatomy, as a decorative element or as a costume accessory. The largest lumbar vertebra measures about 10 cm in width
