1. A torsion resistant vertebrae assembly having a base end member at one end thereof and an articulating end member on an opposite end thereof, said articulating end member having means to control the position thereof relative to said base end member, said vertebrae assembly comprising:

  • a plurality of individual vertebrae adjacent one another, each of said vertebrae adapted to articulate to its adjacent one;

    control means for repositioning said articulating end member relative to said base end member, said control means being attached to said articulating end member and being activated on said base end member end of said assembly;

    holding means for holding said base end member together with said articulating end member and said plurality of individual vertebrae disposed therebetween, said individual vertebrae operable to articulate one on another as controlled by said control means; and

    resilient stiffening means disposed along said individual vertebrae in a manner in which said vertebrae are moveably coupled with said stiffening means whereby as said articulating end member of said assembly is articulated by said control means, said stiffening means provides torsion resistant controlled repositioning of said articulating end member.
