Abstract Horseradish peroxides method of neuronal labeling has revealed a striking similarity in the topographic localization and segmental distribution of the motoneurons forming the sciatic (ScN) and its components common peroneal (CPN) and tibial (TN) nerves, and the femoral (FN) nerve in neonatal, immature and adult rats and monkeys. The FN neurons were located more rostrally to the ScN neurons, the CPN neurons, the CPN neurons occurred more peripherally and slightly more rostrally to the TN neurons. The size spectrum, somatotopic organization and segmental distribution of the sensory, motor and postganglionic sympathetic neurons whose axons run in the CPN and TN correlated with the diameter spectrum of their myelinated nerve fibres showed a similar pattern of organization except for minor differences in the rates and monkeys. |
