For anatomy and kinesiology instructors teaching vertebral morphology at the segment level, this Erler-Zimmer model threads all 24 pre-sacral vertebrae loosely on rubber so each one can be individually examined, rotated, and compared without disassembling a fixed column or handling a fragile articulated specimen.

7 cervical vertebrae, 12 thoracic vertebrae and 5 lumbar vertebrae threaded loosely on rubber. Eminently suited to individual study of the isolated vertebrae with all structures, processes and joint surfaces.

Backed by a 3-year manufacturer warranty.
