Morphological and morphometric studies of the dorsal roots of spinal nerves (segment SI) were studied in nine mongrel dogs aged 2, 5, and 10 months. Longitudinal paraffin sections impregnated with silver nitrate were used, along with semithin transverse sections stained with methylene blue and basic fuchsin. Common features were seen in the structural organization and the characteristics of nerve fiber dispositions at these ages. Increasing age was associated with enlargement of the dorsal roots (most marked before five months), along with increases in the diameter and changes in the ratios of small, intermediate, and large myelinated nerve fibers and decreases in their numbers per unit area.
