[Product Descriptions]

Redesigned and updated with new information, this chart illustrates how one's posture changes due to the different types of spinal disorders, and also explains how other diseases or disorders can cause back pain. The chart shows tumors on the spinal column, ilium, sacrum, and spinal cord, arthritis of the hip, herniated disc, fractures of the vertebrae and sacrum, and the effects of osteoporosis on bones. It also shows the anatomy of a typical vertebra and an intervertebral disc and explains the function of the intervertebral disc. Three dimensions let you feel texture and form. Three-dimensional images, bold titles, and clear, easy-to-read labels make it easy and fun to learn about the body. The durable, lightweight, non-toxic, recyclable plastic will last indefinitely. The chart has a hole at the top for easy wall hanging, and will also stand up on an easel.
