- wherein said central spine comprises a section with a constant cross section;
- wherein said central spine supports a plurality of vertebrae;
- wherein each of said vertebrae are slidably attached to the section of the spine with a constant cross section so as to provide each of said vertebrae a single degree of freedom of linear motion with regard to the spine;
- wherein said constant cross section of the spine precludes rotational motion about an axis along said spine;
