Effects of ablation of the hindlimb on the organization of the ventral horn of the spinal cord in the lumbar region of green lizard embryos (Lacerta viridis Laur.)]

After extirpation of an hind limb in embryos of Lacerta viridis, numerous motor neuroblasts degenerate on the operated side, in the ventral horn of the lumbar spinal cord and the corresponding motor column is reduced or disappears. The lumbar spinal ganglia are affected and reduced on the operated side.
